On the topic of accessories: I have heard that Bare's suspenders ain't worth the $50. People have recommended getting the suspender tabs, installing them yourself, and making the suspenders themselves from a few bucks in REI parts. Whatever you do, get suspenders, though. The CD4 is pretty heavy and you'll want them.
Over my
extensive diving career of 9 months, I have determined that velcro-closure pockets are for the birds. Some neoprene gloves (er, mine) can snag on the hook side. When I do a new suit, I'll get zip pockets.
For thermals, I think the big-name thermals are kind of overpriced. You could pay half as much as you did for your suit with some of them! There are some much cheaper undies on ebay that other users here have had good luck with. (There is a big thread on that somewhere.) This is the seller.

I just had a great, warm couple of dives today in my CD4. You'll be happy with it if you get a good fit.
