Matt, an earth leakage breaker detects current in the Neutral wire only - the theory being that if the currect going out (in the Active) isn't exactly the same as that coming back (in the Neutral), then it's going someplace it shouldn't (like you).

I don't believe the AC inverter has one, but I could be wrong.
Everyone should (if they have a shore-power connection) - but most people don't.

Whether or not you use GFCI Outlets depends on how many you have in the boat. If you only have one, then it's usually cheaper to replace the existing outlet with a GFCI version. If you have many, it's usually cheaper to install the GFCI as part of the AC main switch.

I hope this helps.
