The crazy "Taz" behavior seems pretty normal. The good (or bad) thing is that he'll slow down as he gets older. As Tanza mentioned this is usually called "The Basenji 500".
The biting is also pretty normal. When they get going they are not what we would say is "situationally aware". LOL Usually it's just a quick bite of a pillow before hauling a$$ to some other destination. If you think this is a problem try something like a Lotus ball. It would be great to have him bring it back to you but that might be difficult.
I like to take them to dog parks when they're younger. Lets them do the Basenji 500 and they get to meet a lot of dogs. You just have to be careful in both picking the park and knowing when not to go and/or when to leave. FWIW I've never had a dog hurt at a dog park but there have been a couple of instances where things were definitely not pleasant. Just remember that food and dog parks don't mix.
Since you have room you can use a tease pole and lure to get them chasing. That's good on a couple of fronts.
The sleeping isn't normal but it's not abnormal. Some love to sleep in. Some love to get up early. And some are in between. Sort of like people! LOL
