Holy crap. I haven't been in here for a few days. Been working. Thanks for the guidance Ruslan. I will be doing some of these standing flips tomorrow morning. (at least I hope there is room in the pool) It often feels pretty crowded in there lately. I even walked away without getting swim last time to the gym. Ended up cycling and lifting only. There was one lane that had a single person in it..but he wasn't sharing with anyone.
All other lanes were doubled already. I waited around as long as I could. rant rant rant...I feel better now.
Anyway, I'm going to start with the standing flips in the shallow end you suggest! I know this will help. I am so uncoordinated at the flips.
Based on the amount of good info/suggestions you gave...I'll be asking for further guidance in about 3 months.

I have no confidence in my flippability.:p
