And as far as the list goes, nothing there to really increase that much in HP. Most of the mods there are for getting the power to the ground. Get the rear end if you don't have one already since you have a stick.

only thing on that list of suspension and drivetrain mods that would give any kinda increase in hp is....heads, CIA, tbody, and EWP. for your first mods, i would go with the Cold air induction, then some rear end gears, then work on everything else. if your on the budget i would get some ported stock heads and a cam, along with all the suspension and drivetrain to support it.

Subframe Connectors
Strut Tower Brace
Springs
Shocks
Sway Bar
Panhard Rod
Torque Arm
Tunnel Brace
Lower Control Arms
Front Upper A-Arm
Front Lower A-Arm----- these are all suspention, aka no HP gain, but ET gains
Throttle Body- 8 HP
Mass Air Flow-3 HP
Roller Rockers- 15 HP
Cold Air Intake- 10HP
Valve Covers- 0
Heads- depending on which ones 20-35
Air Inlet Elbow- 1 if that
Ignition coil
Ignition Box
Ignition Wires
Electric Water Pump
UnderDrive Pulleys
Timing Chain- no HP gain but ET gains
Performance Clutch- nothing to BHP but 5 or so RWHP
Front C5 Brake Upgrade
Rear C5 Brake Upgrade
Driveshaft
12bolt Rear End- no HP gain, but ET gains
3.73 Gears- no HP gain, but nice ET gains
LT4 Knock Module
Short Throw Shifter

i mostly rounded up- they are certaintly arguable, just my 2 cents
(ones left black and either only ET gains, or no performance gains, but all are nice products to put on/ essential to make car run better)

Get a lt4 knock module also. You don't want the computer to pull timing when it senses false knock, due to performance upgrades.

And for gods sake get rid of that opti spark A.S.A.P.
