gears on wendsday, what next?

Im getting my 4.10 gears put on my 2002 manual gt on wendsday. I was thinking about doing some more modds. Even though i havent even had the first one done yet. I already know for sure that im gonna get a triax shifter. But i work in a grocery store for crying out loud and this stuff is gonna be hitting the wallet hard. Im not sure about doing any exhaust work because i like the stock sound.(no drone, not loud) After reading up for a while on these forums I chose to get the gears because they are such an inexpensive mod with great results. Are there any others i could do without breaking the budget that would give me around 30 hp or so; around $700 bucks for part and installation or part and easy-self install. Maybe something that doesnt increase hp that compliments the gears.

What do you guys think?

uhh, if you read my first post you will see 2002
