You can, at Rawhide saloon. But if you really want to "play", I strongly recommend you to take 3 cha, and 6-8 int to raise crafting skills, so that you can take at least lvl2 of any profession you like.
Edit:
(ok, 8 luck is waste, take 6, put those 2 into cha, 10 pe is waste if you are not the one who knows what his character is going to do, so take 8 and put those 2 into int, play one week and see what is for you and whats not)
