Flight help - what's with air tahiti website?!!

hi all

am in the process of planning the honeymoon of our dreams and am stuck and need some help. we are from ireland and want to go to french polynesia via LA (so we can go to vegas!) have found flights with air france from LA to papeete. tried the air tahiti website but it said no fares available (for august). what i need help with is getting around the islands. can't seem to find prices anywhere for internal flights. we land in papeete at 10.30pm so will have to spend a night there. so i need to know:

1. how to get from papeete to moorea? how long will the ferry take? is it hassle? it's our honeymoon after all!

2. how much will a flight from moorea to bora bora be?

3. how much will a flight from bora bora back to papeete be?

4. i can't seem to book them on the air tahiti or air moorea websites, anyone else have problems? it keeps just refering to fares below which aren't there!!! would obviously prefer to have transfers booked before we go but if not, is it easy to buy flights there?

i rang trailfinders who quoted us €383 for flights plus €100 booking fee EACH which would put us way beyond our budget. am about to give up and book fiji instead but would love to go to moorea and bora bora so please help!!!!

many thanks!
