Verbal offer from Facebook

I was verbally offered a position at Facebook today. My recruiter told me they are putting together an offer package and they are now asking my expected comp, bonus (bonus structure?), Stock requests, etc. What is a reasonable response? I don't want to low ball myself nor ask too much. For salary I gave a range with the low end being a 15% pay bump of where I'm at now. The rest I have no clue. Also, is it possible they pay off the rest of my lease that I just signed? Any help is appreciated. 7 yoe Texas Hardware engineer (analog/board) TC: 105K
