I cannot help with Byetta info as I'm not on it... but as far as the left over adipose tissue... I would say "Go for the surgery!" It is going to help you a lot in the long run and will help prevent the UTI's. The skin yeast infections could be a huge problem in the long run. You could develop skin ulcers and that is one road you do not want to travel.
You might want to get some 100% cotton men's handkerchiefs or pieces of flannel diaper to make "perspiration pads" to fit under the folds of skin. Fold them and place them where the most moisture occurs and you can change them once or twice a day to keep the area dry. This should help clear up the skin problems. Be sure to wash them in very hot water to help kill the yeast cells and use bleach if you have it once a month or so. Just double rinse to get all of the bleach out so it doesnt' become a skin irritant. I learned this from a nurse in the nursing home I worked in as a teen. It really worked well.
For myself I have found that swimming in a pool really cuts down on the "yeast odors" on my body.
