Welcome to the party, pal!
As far as gun laws, Ohio has it good and they've just been getting better in the last 2 decades. There's statewide preemption on firearms laws so no municipality can enact laws stronger than state laws (although the major cities of Cleveland, Columbus, and Cincinnati may try). All NFA items are good to go.
I don't live in that area but Fremont/Port Clinton area, from my observations, will have economies based around agriculture or tourism. Port Clinton is on Lake Erie and essentially a gateway to Erie Islands, aka Put-In-Bay. If you like to have a few drinks I'm sure you'll end up at Put-In-Bay at least once.
The further south from the lake you get in that area the tourism/service industry turns into agriculture.
Again, welcome, and I' sure someone will be along soon with better housing information.
ETA: National Matches are cool. I've visited but never shot them, but have shot at Perry before. There's a group that hosts pop-up shoots there, which sound like fun. Camp Perry also has a CMP store so if you don't have a Garand yet get qualified and hand pick the one you want.
