Agreed....cut first. Seeing as how you are at 225, and I'm betting you've been there for a bit, you'll hold on to your muscle pretty well. It's the guys who blow up and immediately cut, that end up back where they started.
As for your training, so long as it's a good routine, it doesn't matter. About the only thing I would suggest is that you maybe go with a 5x5 or lower rep routine. I've always found that I perform better, and thus retain more muscle, when using lower reps while dieting. Lower glycogen levels will hurt high rep sets moreso than low rep ones.
It all comes down to diet, insulin control, and some cardio. The details of those previous 3 components can take quite a bit of explanation. Contact AnimalMass, he'll do it for you and straighten out your routine as well. (Sorry Grizz, couldn't resist)
