There's a two-disc set on Steve's Red Pajamas label that gives a great introduction to Steve Goodman. It's called No Big Surprise: The Steve Goodman Anthology. It has one live CD and one from the studio, a total of 42 songs, more if you count medleys separate. While you're at it, you might want to pick up the Great Days Anthology from Steve's buddy, John Prine. It's good stuff, too.
