Hey there Chris, and welcome!

You might want to try some different techniques. WILD is generally the most difficult method, and I've never had much luck with it. My best results have come from MILD and WBTB.

I don't think so. I tend to be a light sleeper also, and I have been pretty successful learning to LD -- actually I had a few naturally since I was a kid before I knew what they were, but since finding DV and learning the induction techniques, I've had many, many more.

I don't really have an answer for your other question, since I haven't worked a whole lot on WILD -- but I'm sure someone else will have a suggestion.
