Svobody is probably the best place to start, it has some of their better songs like "Me and My Ding Dong" and "Remember Me" as well as some solid remixes. Gisela and Treue Hunde are solid throughout, but steer clear of their s/t album.
There's a Pankow box set called "The Art of Gentle Revolution" which seems to come with notes, photos, and even a documentary, but alas, nobody got it for me on Christmas so I can't relay its contents. Most of the information on the net is murky, case in point, their description on Last.fm: http://www.last.fm/music/pankow/+wiki
