Since you already have an intake and exhaust taken care of, I'd get a high flow cat next. A 2.25 inch Carsound cat would be ideal for your present setup. Carsound is, in my opinion, the highest quality cat out there. I see you live in California, so you'll like to hear that the Carsound comes with a guarantee that you'll pass smog tests for the first 25,000 miles of the cat's life. I also see that your Teg is 10 years old, so your factory cat is probably pretty gunky and clogged up a bit inside, so a new cat could benefit you greatly and free up some HP that's always been there. Would cost you about $150-175 (for the cat, hardware and labor) installed, and the sound they make is dope!
Cam gears? Not a cost effective mod for you a this point. Simply installing a new set of gears to factory cams won't do a damn thing, they are a tool used to tune the cams themselves. You'll be paying 2x to 3x the price of the gears for a dyno session and to pay for someone to tune your factory cams. I've never seen any dyno results of someone tuning factory cams, but I'm sure it ain't worth it.
And trust me, your not getting a 10-15 HP jump from an intake. I don't care if its short ram, cold air, what its made out of or what brand it is.
