Ride a lot as in most every if not every day each week but some rides can be short and easy just to freshen up the legs. Don't try to dramatically increase distance and intensity at the same time. IOW, it's cool to stretch some rides and ride a lot but don't also try to make all those rides fast or yo may burn out quickly. Listen to your body, take easy days or complete rest days but if you've got the time to be on the bike and can work it into your lifestyle then get out and ride.
And +10 on the advice above, the best way to quickstart into racing is to join a club or team that works with new riders. It's by far your best move. Check local bike shops or Google for your local racing organization and a list of clubs/teams. This is the time of year that teams recruit for next seasons, here in Seattle each team will host one or more 'meet the team rides' where you get out and ride with folks to see if your interests and personalities match and that's how we get new riders for next season and beyond.
If you live in the states google for your state level bike racing organization and from there you should get a list of teams and things like beginner racing clinics. If you are in the states you'll start as a Category 5 racer (for men) and work up from there but check into teams before taking out your annual license as it makes it easier to list your team on your license if you join the team first.
