You should only try to teach your dog one new command during each training session. Even if you think your dog is good at picking up on things and will have no issues with that, it is much less confusing for you and him if you focus on just one thing at a time.
Teach your dog to be trained, even if you don't plan on devoting a lot of time to special tricks. A dog needs to understand the basic hierarchy of the home and should be prepared to listen and learn throughout his life. Practice the basics like "sit" and "down" in the beginning and introduce something new every once in a while.
Remember that dogs are creatures of habit and anything you start with him will be expected in the future. If you're not keen on him sleeping with you, don't let him do it only on occasion. Likewise, if you don't want him begging at the table, never offer him a bite of people food. He will learn and accept things if you are consistent.
