Yea you will need a spring compressor, and be careful with it if its a cheapie! The ones that are essentially just clamps can fly off if you're not used to them. We used to use them until one day it did, and would have easily taken someones head off if they had been in the direct path of it.

Also, trikkonceptz is right about the shocks. with a 3" drop and stock strut/shocks you will prematurely wear them out and they won't perform that well because they weren't designed to be used with that small amount of travel. You may also need caster/camber plates if your tires tuck in too much when you're done. The best way to lower your front would be through drop spindles, this way you still have roughly the same geometry for your suspension. I'm no expert by any means, a long time ago I had a garage and my partner did hydraulics, lowering, and airbags and such and I just used to help him with the suspension when I wasn't doing my thing.
