woah, this is wierd. I'm 5'10, 130lbs, and just started my workout to bulk up about two months ago. but i do have some advice for you in terms of your workout....
first off, you want to switch the combinations of muscles your doing each day a little bit. some better combos would be
chest+triceps
Back+biceps
legs+shoulders
reason being that when you do chest exercises, you are generally also doing tricep exercises. same with the back. the legs and shoulders combo comes from the fact that that is all that is left and you need at least two of rest between triceps and shoulders... trust me :P
as for cardio on the off days, sometimes I really enjoy a nice morning bike ride, and sometimes i really like just not having to anything while my muscles are so sore.
and absolutely make sure you stretch every day, it will help you a lot in the long run. especially your legs and chest.
also, about the actually exercises you are doing, i may have missed it but i don't think i say bench press or incline bench press or preacher curls or concentration curls in there. oh yeah, and don't forget about narrow grip bench press and skullcrushers. the legs looked pretty good though, good job in that area. as for the lunges, I don't actually do them (but i'm thinking i probably should) so i can't answer you there.
here's a great website that maps out your muscles and then shows you (through video clips) how to exercise them.

hope that helps!
