Heh... I'm here.
Good to do legs first in the week, you'll be fresh, and can put a lot into them. I'd throw in leg press too, and maybe leg curl... you wanna hit legs with like 12-15 work sets (that's what D used to say.) I'd say 4 sets of squats and 3 sets of leg press is pretty good... although I've been thinkin of trying a 5x5 workout on squats and 3 sets of leg press.... I've been throwin in 5x5 workouts in this week, and they're hardcore. I can see why the classic bodybuilders liked them.
do skull crushers. I can't really imagine a tri workout without them, unless you were doing dips and close grip bench. Those are the three hardcore tri workouts I'd say you should shoot for. Some pulldowns are good too, but think of those three as your "squats" of triceps. use one always.
I'd say do arnolds every few weeks, or do shoulder press for like 4 weeks, and arnolds for 4 weeks. Arnold's are way cool.

heh.. .shrugs are traps, not lats
for side raises, I do 5 with a pretty heavy weight, and then drop 5 lbs and do 5 more immediately.. for a set of 10.
think about front raises too.
back.... do some db rows, or one armed cable rows too.
that looks good.
