As for other casted SW radio dramas, there is a short one called "Rebel Mission to Ord Mantell". It is written by the same guy who did the SW radio dramas, Brian Daley. He also wrote the Han Solo books. This story takes place between SW and TESB, and is suppose to be the mission Han is referring to when he mentions "the bounty hunter we ran into back on Ord Mantell" at the beginning of Empire Strikes Back.

This one was not all that well written or preformed. It is pretty juvenile, and obviously aimed at a younger audience. It originally came on a 7'' record, and was published in 1983, not sure if it was ever republished on any other media.

This one was actually made available free for download at starwars.com (within the last year or so), so its probably still up somewhere. I'll try to find the links.
