I agree with the recommendation for finkeepers, too. I've had two incidents of kicking out of my boots when I didn't have them, and there is no more helpless feeling than being in a drysuit with air in the feet and unable to kick to right yourself.
As I said, dry suits take practice. You have to learn to control the air in the suit and keep it where you want it. Once you're good at it, you can run a LOT more air in the suit if you want to. But in the beginning, the important thing is to be safe. If gaiters or ankle weights help you maintain a horizontal posture and avoid feet-up ascents, I don't think it's heinous to use them. Most people eventually discard them, because there really ARE technique things that avoid the necessity of them.
