Low M decisions deep in a tournament

[Jack-in-a-box]

Hi. I have two more theoritical questions, and all comments are appreciated:

1500-men tourney. We are ITM (130-140 players left). I've got 10K, average stack is 35K, BB is 1200 (plus the antes).

1. Semi-tight opponent raises to 3600 in early position. What range of cards should I have to reraise him allin? Raiser has the stack of 30+, FE is close to zero.

2. Semi-tight opponent goes allin for 12K from MP. What is my calling range?

Thanks in advance
