Is shorepower a requirment for the microwave? Does anyone know of a store that would sell the household to shore power adapter? I don't have a marine store nearby but have plenty of lowes, home depot etc.

By an adapter, do you mean an adapter to allow you to plug a standard extension cord into the 30-amp shore-power plug on the boat .... or .... to plug the shore-power cord into a standard household 120-v outlet?
Either way, there are adapters for this, but you won't find them at the local home centers. I purchased some on ebay.
Here's some ebay examples:
http://shop.ebay.com/items/_W0QQ_nkwZ30Q20ampQ20adapterQQ_armrsZ1QQ_fromZR40QQ_mdoZI purchased two of these, for $40, on ebay. One for on the boat and one to keep in the house. They allow me to use a standard extension cord to power the boat when it's on the trailer. Just be sure that you use the appropriate gauge extension cord for the amount of amperage that you intend to be using on the boat. They will also be usefull if we end up at a marina or dock that only has 20-amp service .... and uses the standard household style 20-amp outlets.

Now, If you mean to convert the boat's on-board 12-volt system to run the microwave (or any 120-volt A/C accessory), you would need an inverter. The inverter hooks to the batteries and converts the 12-volt DC to 120-volt AC. However, a microwave pulls anywhere from 800 watts up to 1500 watts (or so). This requires a LARGE inverter and will also drain the batteries very quickly. If you intended to use the microwave in this manner, you would need a 1200 watt (or larger) inverter that is a pure sine wave type (the most expensive, of course), AND at least a couple extra "house" batteries all wired in parallel. In other words, this can get expensive.
