1. No, need V8 tach and V8 oil pressure gauge.
2. 95 Camaro/Firebird LT1
3. Depends. If you want to have 17x9, 17x9.5, or 16x8 4th gen wheels then yeah. If you want 4th gen 17x11's, you'll want a thirdgen rear with a 1" or 1.25" spacer.
4. Need V8 stuff.
5. No need to change brakes but brakes upgrade are good ideas. I don't think a brake pump exists though.

Look at the LT1 swap Q&A at the top of the LTX/LSX section and also check out TexasLT1's LT1 swap website in the Q&A.

1.- will my stock gauges work with the lt1? Yes, use a V6 oil pressure sending unit, or the V8 gauge from a V8 cluster, use V8 tach chip (V6 tach face is a closer match to the LT1's redline)

2.- whats the best year lt1 that i can swap in (i want it to be easy) ? Not many are going to make it any easier, the best choice is what you can find for the $ and mileage though 94-97, is preferred, and 95 would be the most ideal.

3.- should i get a fourth gen rear? That depends on your power goals, wheels you are running, and how much you can get one for.

4.- what about my suspention?, will my stock springs hold up? or should i switch them to iroc springs or something like that? Your springs will be fine, if you are going to switch springs, replace them with a lowering spring kit, installing original thirdgen V8 springs is going to be a big PITA for very little gain.

5.- what about my brake pump, should i change it also? Not sure if you mean booster, or master cyl, but if you brakes are in good proper working order, dont worry about them. Right now focus on doing the swap properly instead of working on too many things at once, same applies to #3 really...
