Hi Thelma, thanks for your post,
You definitely don't need a car until after your stay in Gimmelwald. If you do rent one, you can best park it in Stechelberg and take the cable car up to the village. The car will probably stay parked there during your stay (paid) as most of the region is car free. If you need a car in Austria, you'd better rent one after Gimmelwald. As Slowpoke said, do check whether you need to rent in one country and return in another, as that can be really expensive.
For Gimmelwald, you may want to look into Swiss Half Fare Cards, or perhaps one of the regional passes to save money on cable cars.
