Got you covered: here's the video of all the musical performances in episodes 1-13 and here's 114. They're wmv files because it's easiest in WMM. I have gotten a LOT of mileage out of them because that's my favorite thing about the show so I hope you enjoy :)
Probably your best bet for an episode is Wheels, 109, my favorite one which is all about Artie (and Tina) with bonus Kurt and Sue plots. 103 also has a great Mercedes and Kurt plot but a lot of Will and Finn so I don't know if you'd be interested in that.
