I don't understand why some people are so afraid of gears? As long as you don't get too crazy with them gears are the best mod for the money. I'd get a set of 373's ( I have 410's) if you want performance increase but spend alot of time on the freeway. At 80mph you'll probably be running 2600-2700rpm. Gears always wind up being worse in your head than in reality. As far as other performance mods go, you pretty much have all the inexpensive ones covered you'll have to dig a little deeper in the wallet to continue. You can still do headers, heads, cams, custom or box tune.
I don't know how you drive your car but brakes, suspension, chassis upgrades are always an option.
Good luck
