1. Theoretically , The more you practice dream control the better you'll be at performing tasks, and I think stabilizing an LD is one of them. Sort of like the more you run, you tend to be able to run for longer without getting tired with that said, it's all about the technique; in terms of dreaming and running.

2. I've only hand about 10 LD's or so. I would say no.

3. It's really hard to say because I haven't had LD's in over 7 months with the exception of maybe 3, 2 which were WILD but lost consciousness. The one I did have felt like it took maybe 25 mins. before I realized I was dreaming. It was like a WBTB, I went back to bed and and sort of thought i was just day dreaming, but then I guess later it turned into a dream, after a little bit I realized I was dreaming. This is just one example though.

I always thought of Rem sleep like a "health bar" where the more you dream (lucid or not it doesn't matter), your health bar slowly decreases until no more "health" is left. I got this because from that dream i described, I woke up and did not move but I didn't feel any SP or that I was getting back in the dream. I figured my " Rem Sleep bar" had drained
