I was told to look for tires that can take more than 125 PSI and these got recommended to me.

Now, I've just switched to tubulars mainly because I got a great deal on a bike with a tubular wheelset.

See for plenty of information on tubulars vs clinchers:

I would suggest going down to your local track for a beginner session (you can rent bikes at most tracks) and talk to the instructors. They can probably give you some really tips specific to the track you're going to ride on most. Plus you'll also have a base line for comparison.
