There are many threads about this, but I'll give you the basics (see this thread for more detailed info) -
'02-'05 all have cats in the UP. Replace the UP, get a catless TBE, and some EM. That'll put you at StageII.
'06-'07 don't have a cat in the UP, so it's not really worth replacing. Get a high-flow cat TBE and some EM. Again, that'll put you at StageII.
Mods like an SRI will amplify the sound of your turbo spool and BPV (it doesn't give the power gain like you'd see in other cars).
Don't get an aftermarket BOV - it'll cause your car to sound cool, but at the cost of decreased performance (engine runs rich).
If you want to go beyond that, look into a turbo upgrade (which will require a larger IC, larger injectors, possibly a fuel pump).
When you're happy with how much $$ you've invested, look into a Protune - that'll yield higher #s, while smoothing out the power curve as well (it's a customized map to your car).
Then focus on handling - get good set of swaybars, and sticky tires.
Also do some break mods - SS brake lines, Hawk HPS pads.
