So your proposed schedule would be:
Monday - squatting
Tuesday - Chest (heavy if Friday is DE, and light if ME) and Shoulder Press
Wednesday - pulling
Friday - benching
Saturday - arms, pullups, rows etc.
I'd consider a few changes like: First and most importantly, make sure you're actually doing enough leg work. Heavy squat/deads and whatever accessory stuff you do on those days may or may not be enough, and as a taller dude you might need more direct and/or unilateral stuff to grow quads, hams, and calves.
I'd keep Tuesday's chest work in a moderate rep range (traditional "bodybuilding" stuff) instead of alternating heavy/light, which could interfere in recovery from Friday. I'd also monitor any triceps work on Saturday. Between chest/shoulders on Tuesday and bench/accessory work on Friday, your tris are getting a lot of work, so if you're including much tri work on Saturday, consider mostly higher rep stuff to further aid recovery. Pressdowns or even basic close-grip push-ups above 15 reps can be killer on the muscles and easy on the joints.
Another thing to consider is to possibly have Tuesday as a general upper body day (rows, pulldowns, chest, side delts, arms) and Saturday as a general lower body day (bodybuilding stuff for quads, hams, calves). That way, the week would [i]basically[/] be: lower, upper, lower, rest, upper, lower, rest. But again, that depends a lot on what you're doing in the Mon/Wed sessions.
