Just make sure to bring it up date if your friend didn't. Meaning tranny fluid, if an auto, plugs should have been changed at a 100k if hadn't performed that service. Wires should probably at least be looked at, but with those miles I would replace them. The rest is common sense, as far as air filters, and such. Cold air intake upgrade will help as well if you want to go aftermarket. Just do all those things before the tune.... You don't want to have to go back and tune it again, although it would be free....good luck...welcome aboard. Don't know much about the 2.0 Darts...but, racing is fun, and winning is even better...
