A properly fitting BC should not be floating up on you. What's more, it may be a real distraction and a step in the cascade of problems that can lead to panic. Make sure that the waist strap and cummerbund, if it has one, are cinched tightly, and don't be afraid to re-cinch it at depth to compensate for wetsuit compression (probably not an issue in the pool). You may have too much weight, necessitating a larger air bubble in the BC to compensate and creating the forces that tend to float the BC up. I agree that a crotch strap would solve it, but that's probably not going to happen in your class. Horizontal trim would help too, but that is also, unfortunately, not likely to happen in your class.
Spit's efficacy as a defog seems to vary quite a bit, based on the reports of members here. Perhaps it depends on individual differences in saliva chemistry, though I suspect it has more to do with how much Mike Nelson enters into a particular diver's fantasies. It does have the advantage of always being readily available. If your spit doesn't work well, I can highly recommend McNett's Sea Gold. It works much, much better than my saliva, and a $6 bottle will last for a 100 dives. Once underwater, fogging can usually be eliminated by flooding the mask.
