Looking for critique of plan I'm putting together

Hey guys. I'm currently in a bit of a plateau. After dropping from 270 to 210 after a year of training I've seemed to stagnate at 205-210. I've decided to get back on the diet plan that worked for me and make the push to get to 190 pounds, but I've been going back-and-forth about how to do it gym-wise. The dieting I know is about 80% of the battle, but for some reason I can't stick to a plan, but have decided to go back to what worked with my initial weight loss - a SS routine with HIIT cardio. I'm just looking for some more input into what else I could be doing, should be doing, or if I've got it all wrong and need to stop and get on the right track.

Appreciate everyone's input and thanks! Here's a photo for good measure as well, can post more as needed: http://imgur.com/jE3UJ
