I agree with ironaddict, don't you dare get breast reduction...Seriously!
Well as far as wheight you want to go fairly light BECAUSE YOU'RE JUST A GIRL!!!Hahajk.
Serious talk though, you just want to tone up a bit so if you do high reps with low wieght then you should be good. I'm not a personal trainner but I would recommend what addict said, 15 reps about 3 sets.
