Other then that, and possibly changing the shitty smelling fluid, you probably won't have any issues.
Intake (DIY), colder plugs (AL 104's), 3'' downpipe (which also takes care of the factory u-bend) and tuned PCM (DHP or ZZP, or find a local tuner) are all recommended before you drop to a smaller pulley. If you go any lower than a 3.4 you'll need headers to help reduce knock.
And yes, it's ridiculous how cheap you can get these cars for nowadays. They make perfect dailys. Quick, comfortable, decent on gas, etc.
