Welcome to the forums!

Glad you're considering east TN as a relocation. It's beautiful here.
Nobody's going to get that info for you; that's something you'll have to do for yourself. For schools, utilize sites like greatschools.net and the search function on this and other forums.
As far as jobs in the medical field, it will be easier for you if you center on Chattanooga, Knoxville or Johnson City. There are of course medical jobs in other towns around, but the positions aren't as easy to come by. Luckily there are lots of small towns around Johnson City that might fit whatever bill you're charging.
There are two major hospital systems in NETN, Mountain States Health Alliance and Wellmont. I would start by looking on their websites at job listings to see what sort of positions are available right now.
I'd also pull up a map and decide how far out from Johnson City you're willing to live. A 20-30 minute commute could easily include eastern Greeneville, Erwin, Gray, Limestone/Telford, Piney Flats, Bluff City, Elizabethton. Then I'd probably start looking for info on each of these cities/communities to see if they might fit my criteria.
