Must resist M:tG. Boardgames are my methadone :)
Further details from the FAQ:
Q: The rules state that you may load and move transports. Can you move and then load? For instance I have an empty transport in sea zone J and I move it to sea zone K and load 2 infantry on it from Malaita (in order to evacuate them), is that allowed? Or must you do it in the order load first and move second?
A: No. Load first, move second.
Q: The rules indicate that "you may load land units and supplies from adjacent island zones onto transports." Can I load a single transport with units from more than one island, or must the units that load onto a transports originate from the same island?
A: You can load up your transports from different places as long as the transport has not moved yet.

Also don't forget this VERY important detail:
The rulebook states that players get 5 reinforcement points, plus 2 per island they control. This is incorrect due to an error in the rulebook. The correct reinforcement scheme is that each player gets 10 reinforcement, plus 4 per island they control. The game is playable either way, but Avalon Hill recommends playing the correct way (10 and 4 per). We are sorry for any inconvenience this causes.
We didn't notice until we had played a couple of games, which was annoying.
