Yea, like Carleton said, 140psi is the minimum pressure. That'll help a lot.
You'll probably notice that you're racing against the same people every week. Through the season you'll get to know everyone and how they race and you'll make some friends.
One of the things that I really enjoy about track racing is the time in the infield between races. After racing together for years the men and women I race with have all gotten to be friends.
