After all breathing mods are done, whats next? 11:1 Cosworth Pistons or JWT Camshafts
Which of the two would make the car more power? 11:1 cosworth pistons, or some JWT or S1 camshafts...

Description
The piston is one of the most important components within the engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces of 8500g. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth pistons are manufactured using the same methods as our Formula One pistons and include features such anti scuff skirt coating, ulta-strong pins, polished top and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston design
Anti Scuff Skirt coating (Coscoat 1000)
Polished top (reduced carbon build up and stress relief
Manufactured from proprietary alloy (CosAL 010)
Ultra Strong Pin
Patented Anti-detonation bands
11:1 Compression ratio
Set of 6 includes Pins and pin locks
Performance Ring Sets available separately
JWT S1 Camshafts:
260 DEG DUR. / .428"(10.9MM) LIFT, INT. ADVANCED 2 DEGREES. ** NOTE: THIS CAM UPGRADE MAY REQUIRE THE IDLE RPM BE SET TO 850 RPM TO PREVENT POSSIBLE STALLING AT IDLE. 2004+ LEV II VEHICLES DO NOT ALLOW FOR IDLE ADJUSTMENT AND SHOULD NOT USE THESE CAMS WITHOUT SEEING OUR TECH SECTION ON IDLE STABILITY MODS. WILL NOT WORK ON 2005+ REV-UP ENGINE WITH EXH. CAM CONTROL.

both 
if you had to pick one, I'd pick cams with valvetrain upgrade.. port and polish if you have the money.
Gaining half a point or so in compression won't make that much of a difference by itself.

I would say that the cams would be better only because doing the high compression really stops you if down the road you want to go with forced induction of some sort
