I have a 14 1/2 hour overnight layover in Oslo. I am an American citizen and for that leg of the trip, I will be traveling from Tromso, Norway to Newark. I've read that there are places (safe) to sleep in the airport. There are hotels outside the airport. I have several disabilities and would rather stay at a hotel. How would that work with customs and such? I also have an 8 1/2 hour layover in Newark the next day. I really didn't pay enough attention to the return trip times. Help!

In city center, you can look at this hotel:
I guess my major question is how difficult would it be to leave and reenter the airport?
The last link I posted should provide you that information. Furthermore, the first hotel link I provided have a shuttle airport service that can pick you up from airport and return you back for your flight.
We spent a night at the Radison Blu Oslo Gardenmoen in March. No shuttle needed, just a short walk to the terminal. We arrived mid-day by .chartered bus, too early to check in but could leave our luggage with the Radison. The OSL terminal train station is a short walk from the hotel if you want to visit Oslo. We had a nice light dinner at the Wagamama Restaurant in the before security side of the terminal a short walk from the Blu. Hotel set a very nice breakfast.
Presumably you would be arriving at the domestic terminal (Gates A, B or C) and just walk out. You would need to go through security the next day and would need a boarding pass/ticket and passport to reenter then board your international flight (Gates D,E or F). OSL is a pretty compact airport.
If you have checked bags, check with the airline about baggage transfers. With a 14.5 hour layover you may have to pick up then recheck the bag(s).
You wouldn’t need to go through immigration/passport control or customs since you are coming off of a domestic flight from Tromso. You deal with customs when you return to USA. Get a hotel room in Oslo, maybe a day room in EWR.
