BR For a Baby NL Game

[CripAces]

So I have three questions and hopefully you guys can help.

1. Whats the right BR for a 1/2 blind 100 Max NL game?

2. Whats the right BR for a 1/1/2 blind 100 Max NL game with 4 to see the flop?

3. What is the the pertange chance(if it is possible to calculate this) of my risk of ruin first starting out playing 2 and then what for playing game 2 if I start with just a grand?(Assuming I can beat the game in the long run, which I am confident that I can)

Thank you for your help in advance.
