Hi Wetpup,
Mostly everything has already been said. Both options, land based dive shops and liveaboards are good ones to dive Truk since the wrecks are only 40 minutes away - by speed boat - from the shore.
Liveaboards, though, are floating hotels so you are living on the top of the wrecks which allows you to dive the spots when there is nobody yet. The Truk Siren will have open dive decks so you will be able to choose when you want to dive.
The Truk Odyssey and the Truk Siren are both good choices to dive Truk wrecks.
Cheers,
Leticia
