That's a good call.
Gets expensive after that

Exhaust is more cosmetic on n/a cruisers, depends on the look you want.
Avoid throttle body spacers, they don't work.
A header is a reasonable choice later, just search around for types that are reliable and good quality (JBA, etc.) avoid Hedman's.
To really put more power (real power) not factitious HP "add on bolt on claims), you'd have to go aftermarket for a turbo or supercharger. If you want to pull about 200hp, you could spend 5 grand buying and having a supercharger installed. Or a more adaptable solution is a Hahn turbo. However, both require some degree of maintenance know how in terms of proper tuning. If your not ready to do that, then that's not the choice for you.
I think the first couple of suggestions would help make the driving experience more fun. If you have a 5spd, it is peppier than the auto. Try a Hurst shifter with more solid bushings...helps with shifting efficiency.
