I would suggest an air blower (they are noisy but add a lot of action) and bubblers (air injectors) in the seats and footwell. Makes you feel like you are soaking in a glass of champange! )The jets will be basic since the more jets the bigger the pump you will need and if you go with a single and not a dual system you can't go too big or the pool will not filter properly and your electric bills will be crazy. Go with at least a 2 speed pump (variable speed and controller is better) since that way you can run the pool and spa on low for filtering and circulation and the spa on high for tubbing.
