Yeah, your assessment is, by my amatuer reckoning, about right- your bench is fine for a novice to intermediate lifter your size, but your squat is something more like a 10-rep backoff set than a max, and your deadlift is properly a warmup. Presses are weird, but they can always stand to get better. If you didn't gain a pound, you should be able to tack on at least fifty pounds on your squat and a hundred on your dead by just doing your fives three times a week. And assuming you're lean-ish, a little poundage probably wouldn't do any harm. Milk. Squats. Milk. Squats....
And don't be afraid of a big bench. It's only a problem if it's big because it's easier than squatting, hip at your gym and you chickened out of heading to the rack, which I suspect from the numbers might just have happened a couple times;-)
Pullups? Sure, everyone can stand more pullups. The days you don't deadlift, do three limit sets after everything. If you get 10 or twelve on each one, do weighted one workout, unweighted the next. And sure, do some on trees when you get up from your desk. It's just that pullups have more characteristics of an assistance exercise (albeit a super-functional and useful one) than they do a core lift, and they probably should be treated somewhere in between the two. Do more, don't wear out your back before you deadlift, and all will be well.
You're not really strong enough to be doing a heavy-triple, percentage-based program, IMO. 3x3 @ bodyweight isn't going to do much.
You mention you're just now learning the clean, and your squat and dead are low- do you feel comfy about the technique? I know the first time around I chickened out because the squats started feeling really heavy, and I got spooked, thinking my technique was solid when it was actually pretty sorry. Do you have the books and have you read them-and tried the experiments and stretches, and then read them again?
Squats and milk, my friend.
