Do you raise her preflop?

The problem here is the SB. He has a big stack, and might be inclined to call you with some strange cards. Pushing is better than raising to 300, but really I think maybe the best option is betting enough to truly pot commit the BB while driving out the SB, and allowing yourself to room to fold if the SB puts to all in. I think betting 450 here would be good. If you get played with by the SB, you'll still have t600, which isn't bad.
