What would you do in the event of a emp attack or major solar storm like the one in the 1840s? All electrical devices dead and unable to be rebuilt, all vehicles post 1980 dead where they are, all planes fall from the sky our country basically time warped back 100+ years and no possible emergency help coming for over a year. What do you do?

Knowledge of snares and traps to start getting squirrel and birds until the deer population starts to edge into my neighborhood.
Just a start...

I don't prepare for specifics. I prepare for generalities. Things like food, medical supplies, defensive weapons, ammunition, precious metals, books (especially books that teach skills), and ways to ensure a supply if the basics (food, water, shelter, security, etc.). Don't prepare for everything, prepare for anything.
Also, storing backups of sensitive electronic neccessities in metal containers or safes (which will act as something of a Faraday Cage) is a good way to protect them from the effects of EMPs. And anything hooked to a hardline is toast.

Prep for anything, and be good to go regardless of what happens (even if all that happens is nothing).
Metal safes are really nice for storing some things. I keep a backup hard drive in my gun safe for the security factor, but that would probably shield it from EMP too. Of course, finding a computer that can access that information is another problem...
Side note, since you're talking EMP specific -- a lot of smaller electronics will survive. An object needs to be big enough (or rather, have enough electronics and be of some dimensions) to induce a current that will damage it or destroy it. Of course, most of those small electronics rely on batteries, which will die out without replacements or their charger (chargers won't function since the power grid is out, but you could conceivably have batteries survive and use them for things like flashlights, watches, red dot sights, etc) Generally, the more complicated or the larger an electronic device is, the more susceptible to damage/destruction by EMP.
One thing I really want to add someday to my survival tools is a solar powered battery system. It's basically a big battery you can charge up with solar panels. I'd get one and put it in a Faraday-cage like container, but it'd be nice to get power anytime the grid dies for a few days (bad storm takes out power lines, Xcel Energy screws up again, EMP, whatever). It wouldn't be a lot of power, but it would be enough to make some things a little easier or last a little longer. And it'd be a lot quieter and more long term than any gas powered genny - draws far less attention to oneself with a discreet panel charging a battery than you are with a genny running.

The problem with simply surge protecting is 2 things actually. The EMP happens too fast, and it induces current on BOTH sides of the protector.

There are 3 waves to an EMP, if memory serves correctly.
The first is caused by the initial release of energy from the atomic detonation. It is almost instantaneous, and has little effect on most electronics.
The second is the blast pushing a huge gaping hole in the earth's magnetic field. This takes fractions of a second. It does set the stage for some damage, but in and of itself is only dangerous to the most sensitive of electronics.
The real damage occurs when the earth's magnetic field forces itself back into place. As the magnetoshpere moves, it induces some level of electricity in anything metallic caught within the fields movement. Metal moving in a magnetic field creates electricity, or in this case, the inverse. This is when the real energy builds up in the power grid, and when the damage occurs. And the power has time to build up, because the planet's magnetosphere moving back into place can last for up to a few minutes. The more metal something has or is connected to, the greater the energy produced and conducted. So hundreds of miles of power cables will produce enough to fry most anything wired to them. But something like a simple circuit in a flashlight will pretty much be untouched.
I mentioned storing things in metal safes earlier, to shield them from the effects of an EMP. That is because the solid metal container will block the magnetic field, and the wave of energy, by conducting electricity through itself and keeping it's contents untouched. It's basically a Faraday Cage.
If I recall correctly that is.

The E2 component is generated by scattered gamma rays and inelastic gammas produced by weapon neutrons. This E2 component is an "intermediate time" pulse that, by the IEC definition, lasts from about 1 microsecond to 1 second after the beginning of the electromagnetic pulse. The E2 component of the pulse has many similarities to the electromagnetic pulses produced by lightning, although the electromagnetic pulse induced by a nearby lightning strike may be considerably larger than the E2 component of a nuclear EMP. Because of the similarities to lightning-caused pulses and the widespread use of lightning protection technology, the E2 pulse is generally considered to be the easiest to protect against.
The E3 component is very different from the other two major components of nuclear EMP. The E3 component of the pulse is a very slow pulse, lasting tens to hundreds of seconds, that is caused by the nuclear detonation heaving the Earth's magnetic field out of the way, followed by the restoration of the magnetic field to its natural place. The E3 component has similarities to a geomagnetic storm caused by a very severe solar flare. Like a geomagnetic storm, E3 can produce geomagnetically induced currents in long electrical conductors, which can then damage components such as power line transformers.
So there's a big wave of damage up front, followed by the nasty stuff when the Earth's magnetic field forces itself back into place. The second stage isn't much worse than a lighting strike, and most surge protectors can protect that. They just can't handle E1 (too fast) or E3 (current induced on both sides of the protector)
