OK, i'm going to assume that you know nothing about exhausts, so if i'm telling you stuff you already know, please don't be offended.
Lets pull up the handy-dandy WRX exhaust diagram
As far as an uppipe goes, please go to our vendors forum and check out the various vendor's uppipes. Uppipes come in two forms: solid and flex. Any name brand uppipe will suit your needs fine,
Again, any name brand downpipe will give similar gains. The only exception is the HKS. It's the only "blank plate" name brand downpipe on the market, and the general consensus is that it is not as desirable as the bellmouth or divoced-style downpipes. Please see the Engine Performance sticky located in this forum for more information.
By custom exhaust, I believe you mean catback. A catback runs from the rear-catalytic converter/midpipe to the muffler. Any name-brand catback will suffice and give similar gains. However, it is up to you to decide which style and sound you want.
Please, read Ebr0t's engine performance faq. It is very, very informative.
Yes, most people get rid of their catalytic converters, this results in a tremendous performance increase and is 100% necessary if you plan on peforming major power upgrades on your car. If you are not comfortable with going catless, you can always run a high-flow catalytic converter.
