It's fine for Uni. I've been carting a 15" to and from Uni (4 hr total travel per day, car, train, walk) every day each semester for four years.
Get a nice backpack for it, and maybe a hard case too. I have a Belkin bag, and think it's great. I had a Targus bag before that, but found the bag was too big.
Unless you're OCD about small scratches and marks, I wouldn't bother with any permanent skins or protectors. You just want a hard case so if your bag is hit, dropped, kicked, etc, your MBP won't be harmed.
And obviously don't leave your computer/bag out of your sight, unless it's with a friend, and you expressly ask them to mind it.
