Stretch marks : I dunno how but mine suddenly decided to fade away over time. I had one nasty one around the stomach area where it looked red but somehow, it's gotten less obvious.

"Medals of Honor" for losing weight.

Cycling : Try to vary the intensity and see if you can do slopes as well. I like Crosstrainers, especially the Summit ones. Those are my thigh busters at the moment!
