Spa is a nice little town with plenty going on and a choice of restaurants. I'm desperately trying to remember the name of a great little B&B we stayed in, about 10 mins from Spa towards Malmedy. Very pretty place, out on its own a bit but incredibly peaceful as a result. Restaurant only open a couple of nights a week but has great reviews.
You can access the race circuit to see what's going on - usually some sort of track day.
Remembered by looking at old photos it's called Le Soyereu. http://www.lesoyeuru.be/
