$250 total is a nice deal on that bike. Hopefully, you'll get to know your bike a bit better and learn to service it yourself. It's not all that complex, and most basic tools are affordable.

If the shop didn't do it already, check (or get someone knowledgeable to check) your hubs, wheels, headset, and bottom bracket for adjustment. If anything feels gritty, tight, too loose, or otherwise krunky, fix it soon.

Oh, and you may need new brake pads. Even the cheapies are better than dried out older ones. Welcome to to the archaic, murky, but ultimately satisfying world of bike maintenance.
