Puppies are not for the faint of heart, they are like having a 2 year kid....forever.
Good advice. If he doesn't go while he's outside, crate him as soon as you come in. In addition, a technique I've seen used that works well is 'tethering' the dog to you at all times. Don't give him free run of the house.

Here's one website for some basic training techniques, and one of them talks about the tethering.
