97 Accord LX question

Ok, here's the deal: I just inherited my mom's 97 Accord LX 5-speed. I was wondering how many horses she's putting out (everythings stock at the moment). Also, I want to get the most HP for the buck, seeing how I still gotta pay insurance, etc. The only mod's I have now are Altezzas (my neighbor broke one and covered the replacements) and dual exhaust. For the outside, I want to get some red badges, a type-r grill, and some xenonon bulbs. Interior I want to get a new knob (torn between a Skunk2 and a Spoon) I saw Type-R boots (black w/ red stitch) but those are just for civics. Do they make them for Accords? Also, can you recommend a good short shifter?
For performance, I want an HKS muffler, maybe a Random catco, and AEM CAI? How much power would i gain? Also, i'm a non-V-tec, 4 cyl.
I don't want to make my car all gaudy and shit...just a little Type-R styling and some fun stuff under the hood.
One more thing...what can i do to increase acceleration? Sorry for all the questions- I'm a tuning virgin :/
