Couple of things.
One: welcome to PL. It's awesome.
Two: don't worry about getting to a 'good' standard. Being a bloke anywhere between 198 and 275 lbs makes getting to a good standard very, very tough. Its tough in ANY weight class but the 198, 220, 242 and 275 are the toughest (well, they are where I am). So, just find a local meet 10 to 15 weeks out, sign up and compete.
Three: leads on from two, no-one apart from you cares how much you total. You'll get cheered on no matter what and will get tons of help and advice.
Four: you might want to reconsider how you train a little. That is a lot of days training. Most PL training seems to be three to four days a week. You can do some condition but you want to be careful it doesn't negatively impact recovery. Try something like Cube or Candito or even Mike T's RTS. I've also heard good things about 5th Set For Powerlifting They're all dyed in the wool programs. In short, drop the a bunch of the cardio.
Five: you'd be surprised how little (read no) cardio you need to drop fat if you're eating right. My bodyfat has dropped using the very, very simple carb cycling approach set out in 'Carb cycling for non counters' from T-Nation. No conditioning. Nada. Zip. All I do is walk 4 to 8 km at a relaxed pace almost every rest day (and I only lift 6 days per fortnight).
Hope that helps. Best of luck.
