With the 350 the best way to gain performance but not extra power is weight reduction as Ynot says.

Remove as much of the fat from the car as you feel comfortable with the liners on the hood and in the trunk are a good place to start, then ditch the spare and the tools that become redundant without the spare but keep the towing eye and the pack of fuses with you in the car.

Then you start to move onto things that cost money but make a more noticeable difference stuff like lighter wheels and CF parts (proper CF not the stuff that looks like it).

For extra power most cost efficient will be insulation on the airbox if used with a lighter box its still a weight reduction that helps lower intake temp also chroming the inside of the intake manifold thats again acts to keep the heat only where you want it, new exhaust and headers and insulate them if possible that causes the temp to rise this promotes scavenging from the cylinders and helps keep carbon away.

Basically getting more and more expensive until your at 55 price ranges and then on up to SC range.
