Nice! You've got a good starting platform. Like others have said, define your goals first, then research like crazy, come up with a good plan, hunt the deals patiently, and don't get sucked into deviating from the plan.
One day when you have time, read about 50 or 60 pages on here, to see what these other guys who have amazing builds have been through. It'll help you shape your own vision and goals, and maybe talk you back from a few things that sound cool at first. I've toyed with forced air ideas several times, but the posts that discuss the challenges bring me back to the fact that my street car does what I need, and doesn't give me challenges I don't need.
Welcome, and remember (from one who's been there) the car will always be there, the kids won't. Hopefully they get into the hobby with you--that's the best of both worlds!
