1. if you play full ring and just starting out, yes. if you play 6-max and just starting out, yes. so, yes. it's probably way to much, you could fold some more preflop.

2. tight aggressive, ABC poker. don't get fancy. read stickies in the beginner forum, read hands, post hands, ask everything!

3. do you raise your non-premium hands too? if 4xbb is not enough, raise more to isolate. don't go crazy though, i think someone else has a better idea about what to do about this.
