Hey Chelley have done this leg several times all for surfing trips back in my single days 1990 - 2000.
Have flown from Bali to Lombok and from West Sumbawa to Sumba.
Flew with Air Merpati, boarded local buses interesting adventures and cruised on the pearliney ships (not sure about the spelling) all around this side of the archipelago.
Back then the authorities allowed us to drive on the car/public ferry and use the car in the other islands this made life a little easier, I think now days they don't allow for this to happen. If you are going to Lombok we used to rent cars off a guy his name is Homi Ho business name oriental car hire he was always reliable.
You'll have a great time I suggest heading north around the island of Sumatra lots of interesting places there.
Only piece of cultural advice is to dress appropriately with respect to the local religion best of luck.
