I agree about the suggestion regarding dips. I would do chinups though, I love doing both chinups and rows, but then I really like hitting my back... About the squats and deadlifts thing, if you can handle them together, then go ahead and do them. I almost always do both in my routines, though not always. It works better if you do a split though. For instance, I really like AM/PM splits, with deadlifts in the AM and squats in the PM.
