Here are my personal suggestions:
If you're staying with the OEM throttle body, you probably don't need the coolant lines going to & from it. They're there to keep the TB warm enough so the butterfly won't freeze open in the wintertime, however in Houston it rarely gets that cold, even with the JT pressure drop across the TB.
Resist the temptation to remove the Evap system, and whatever you do, DON'T plug it off and try to seal your gasoline tank. The tank needs to be able to breathe - as fuel goes out of the tank, that volume needs to be replaced with air, and vice versa. Plus a working evap system will keep your garage from stinking up. You can reroute the canister back to just after the intake air filter and it'll work fine.
Install a good oil/air separation system for the engine crankcase. The simple OEM PCV system probably isn't sufficient for a 20 year old boosted motor. You probably have "some" blowby now, so rest assured you'll have a lot more when you're under boost.
Obviously your brake booster needs to keep its line, and I believe there's one that goes to the P/S also?
I'm sure there are other lines, but you'll need to figure out the function of each one and decide whether you need it or not for your application.
