Orangutan/nussa Tengarra Trek

Hello again, I recently posted a thread about a trip I'm planning to Indonesia in 08/09. The first part of my trip I plan on visiting one oft the Orangutan preserves. I know they can be seen in Borneo and on Sumatra. I'm trying to decide where to go. I'd like to stay away from tourist traps and Ive read some disturbing stuff about camp leaky and another spot in Borneo. Can anyone recommend a place our a tour company. The rest of my trip(3 weeks) will be spent traveling acrossthe Nussa Tengarra region west to east. I've never been to Indonesia and really don't know what to expect except for what Ive read.
Is this trek doable in 3 weeks?
Do I need to book rooms in advance or could I find lodging while there?
Thinking about renting a motorcycle (i'm experienced driver) in lombok, is this a good or bad idea?
Would like to do a lot of snorkeling and some surfing, what areas are best?
Any must sees or islands I should skip? Any help would be greatly appreciated.

Thank you to all the responders to my last post

Hiya, sounds like quite a trip... I've visited the Orangutan's at Bukit Lawang (Sumatra) & Sepilok (Sabah), both very interesting... Bukit Lawang & Camp Leaky are quite a distance from Lombok! A motorbike would be a great way to get around Lombok, just remember the bigger the vehicle, the more right of way it has on the roads! There is some nice snorkling on the Gili Islands, not sure about surfing in the region apart from Bali... you would also need to allocate 1-2 days travel time between islands in Nusa Tenggarra... things of interest would be the rugged coast lines, Komodo dragons, Keli Mutu volcano, batik, buffalo races & very few tourists... if you had more time, a ferry trip to Alor would be worth while... have fun!

Hi Craig,
