Sit back lad, and read, read, read. Leave the
clubs in the bag (well, ok, except maybe your putter. I believe that putting is a total personal-feel thing, and that there's no 'right' way to putt. The pendulum is proper, and I'll agree with fixed hands (no wrist break), but I've played with guys who are as far away from 'textbook' as you can get, and they putt the lights out.)
Wait for your full swing lessons - there's no point in creating bad habits that will have to be fixed. After your lesson, work on what you've been shown. A good instructor should have your swing working great in a dozen lessons or less, depending on how well you do the drills, and how much you practice.
I've seen it many times as a basketball coach of young kids - if you teach kids to do one or two (UNRELATED) fundamental things between sessions, and that's all they focus on, it's much easier to build good fundamentals. It's the kids who go beyond the fundamental drills that have more problems, because we have to iron out their bad habits (which feel 'natural') in order to give them good mechanics.
So relax! You're just getting in, and unlike most other sports, you can be golfing for quite some time to come. Enjoy your lessons, do your homework (reading and practice) and enjoy this wonderful (and frustrating) sport.
If you want to read some great lessons, do a search for Leslie King. My swing is progressing faster than it ever has because I've been reading this guy's lessons for a week straight now.
