Having completely disassembled and re-assembled a car myself (including rebuilding an engine), I think I can offer some advise.
You'll need a 3/4" ratchet for breaking loose suspension components. An impact wrench would be even better. For many things a 3/8" drive just isn't going to cut it, especially if there's rust involved.
Yes, you definitely need anti-sieze. Just about every bolt you put back in the car should be anti-siezed.
A really nice wire stripper/cutter.
Dead blow hammer - usually plastic and filled with steel shot. You use this in areas you can't risk damaging with a steel hammer.
Fender cover
Bolt-out - when you're at your wits end due to snapping off a bolt or rounding over a nut beyond hope, these will save your butt. WONDERFUL tool!

If you plan on doing brakes, you'll need some standard C-clamps. Brake bleeder kits also come in handy.
Most of the speciality tools you'll need for suspension/engine work...pulley pullers, tie-rod tools, ball joint breakers, strut/spring compressors etc can be rented from most auto parts places.
A big vise also really comes in handy for pressing out bearings, etc.
Hope that helps!
