Hey, I've got the same power rack as you do! Minus the pulleys, anyway. I don't have quite as much weight sitting around either (a 300# set plus 4 more 45# plates is all I've got, and no dumbbells). For lifting I train like a powerlifter although I've never lifted competitively. I love squats and bench, though I wouldn't say I'm that good at either. My grip is too weak to really even discuss deadlifts. With straps I do fine, but without them. . .

Lately I've been doing a routine based on the Westside Barbell Club method - I haven't seen much of a strength improvement yet, but I'm able to lift the heavy weights quite a bit faster now so I know the power is coming along. Just a matter of time before the weights start creeping up again.
