Hi spacestixx and welcome to Cardschat.
Start low and slow to see what happens. If you win good to start with, keep in mind that it can change without any notice.
With a $100 BR, you could start at 2nl or 5nl cash tables, and no more than one table to start with. You could start at $1.10 or $2.20 MTTs buyins, and only one of those at a time.
You will get other replies to your tread and I'm pretty sure that one of the things other players will stress is to not play to many hours a day. Being tired while you play is not good. And if you will step away from the games and come back fresh, you will be glad you did. If you want to test this, one day play 12 hours str8, and the next day play 5-6 hours, and get that many hours rest, and you will see the difference. GL to you no matter what you do or play
