depending on your money sitaution...I'd go cold air intake (AEM, Injen, or Bumi), and exhaust to match the downpipe that should already be on your vehicle, like 3' downpipe I duno, exhaust wise I have cat-back Magnaflow 2.5' and I love it. Better waste gate and blowoff valve is always good, but what would really help would be the APR computer chip, which I have and it's around $500. The sites I always go to is www.fastaddiction.com, www.goapr.com, and www.eurosportacc.com....try those and see what you come up with.

Yeah, I agree with bagel, very important for turbo systems to have equal size exhaust to your downpipe for maximum performance. I do not recommend though, spending money on BOV's (blow-off valves) you pay for the name and the type of sound it makes when it blows off, even a cheap Monza will do the job well. We use the Monza in our kits because it keeps the whole costs of the kit down and it does the job well. Dont' pay for noise, unless you're into that. Won't increase the efficiency in diminishing the compression surge. Unless you have a faulty BOV to begin with.
