Well fat is fat on your body so there isn't one exercise that will get rid of your love handles. If you do a search on the web for ab exercises there are loads of them. Look up 'supermans' for your butt, those will help. As for the bra thing, I'd just go to the store and try on all different kinds and see what you like best. Put your shirt on over it and see how it looks and pick one you find comfortable and flattering.
