Mystic, I would encourage you to find agility classes. Make sure you ask to be postive that they use positive reinforcement.
Right now your dog needs to know basic obedience. Sit, down, come, and stay are necessary. Extra commands can be taught to make the transition to agility better such as "here" and "right or left".
I would start with simple focus excersizes. You want your dog to be focused and in tune with you and your body language. Teach him "watch me". Whenever he happens to look up at you, reward him with treats or a favorite toy. As soon as he has started having good eye contact with you and you are successful with those obedience commands mentioned above, you are ready for obstacle training!
I always start with Jumps and Tunnels. At first, only have the jumps at 1/4 the competition height(for you that would be about 4 inches). Once he is performing the jump at that height, start proofing from odd angles. And, once she is a year old, I would start to slowly raise the jumps.
Tunnels should be taught with tons of positive reinforcement. First start with very short tunnels, such as 10 foot, that can be easily shortened to a mere 3-4 foot. You will need to get a friend to help train this. At first, have the friend hold your dog, while you tease him with a favorite toy/treats. Once he is very interested, call him at full speed. Once he is used to the friend holding him back, introduce the shortened tunnel. Hopefully he will come straight through, but if you have, to crawl in a bit and lure him with a treat.
Once you have got him running through the tunnel towards you, start running with him and giving him the command. At this stage of learning, it may be best to put "blocks" up so that it is nearly impossible to do it wrong or miss the entrance of the tunnel. Set the dog up for success, as they say!
Eventually you will want to proof this for odd angles as well. Once the tunnel is getting very consistant, you can start making slight turns in the tunnel.
Please, ask if you have any more questions!
