Reminds me a lot of my late gt; nice find with a 5 speed!
Definitely do suspension. KYB GR-2s with H&R sport springs and rear spacers worked out great, and gave it just the right drop. Not really much to do as far as power goes...the only thing you're really looking at is an intake, msd coilpack and an exhaust. Axleback was the only thing I could ever find for the 2nd gen unless you want to go custom.
Also, find a rfrb grill
