Disciplining a one year old?

My son is 17 months old and I can't figure out the proper way to "discipline" him. 
I know that he's too young for anything like spankings and time out, and that I have to be careful what I discipline him for because he's just exploring.. But he's getting bad about biting, pinching and hitting. 
He's also recently started climbing on top of the kitchen table, and he knows he's not supposed to because he watches you while he does it and laughs when you tell him no. 
Any suggestions?
