my numbers at 238, RAW also, are not that much better that yours. I squatted and DLed 440 in my first meet, only got my opener on the bench of 285 because of a technicality. my goals in my October meet are 500 DL and SQ, and solidifying my 315 bench.
so far PL to me has been about pushing my limits, setting new goals and traning for them, not about competing against other PLers. By all means sign up for a competition, they are exciting, you meet great individuals and maybe get to see some really strong mofo's pushing some really heavy sh.t around. In my first meet I got to see Richie Briggs from Big Iron gym hit a 858 bench...
my only advice is start adjusting your training to how you will be judged so it is not a surprise. touch your chest with a pause, wait for rack commands, hit parallel, dont hitch on your thighs during DL, etc....
