Come back vote here. Start off in Masters and see how you feel. P/1/2 seems like a lot of stress if you're questioning it already.

I had a great 1st season in 1992, upgrading from 5 to 3 between June and September in Colorado. Then I burned out racing 3s as untrained pack fodder for 3 years. So I hung it up and just rode for fun and commuted. Every year or so I'd race 5s for the hell of it.

Well, last year I got my license back as a 3, and did two races as pack fodder in M35+. Trained well in the off season, and did 3 races this year, winning the last one. I'm having a blast, and I've got a couple Houston crits coming up in May that I'm really excited about. I'm not racing anywhere near full time. I think I've missed about 12 races this year, intentionally -- don't want to stress the home life too much.

Have at it!
