Switching to upper/lower split - suggestions of what to add?

I started lifting a few months ago and was doing full body 3 days a week. I'm planning to switch to a two day upper/lower split though. I think I'll get more out of each of them that way now that my weights are getting higher.

My full body routine consists of high back squats, deadlifts, chest press, over head press, row, assisted chin-ups and pullups, standing calf raises, dumbbell lunges, and some minor ab work. I've put the chest, OHP, row, chinups/pullups and ab work in to upper and am adding lateral raises, tricep cable pulldowns and bicep curls. That leaves squats, deadlifts, calf raises and lunges in lower.

My question is ... what else would you suggest I add to lower? And would you recommend any changes/additions to upper?

Thanks!
