FD Autoworks is great for a local shop for just about anything, including your intake and exhaust. They're really the only place around for our subys. For tuning though I'd go to someone like EQ or GST because they have a dyno and a lot more experience with tuning. Let Andy know what your long term plans are so he can help with advice. He has no problem with you going elsewhere for some of your work just keep him in the loop.
The Trinity Touring Club is primarily an autocross club but we do sometimes do other things like touring the mountain roads or social gatherings. No dragracing but some of us do enjoy it.
