they had webisodes and a novel and a few comics that supplemented the show though I only got hands on the comic because I couldn't view NBC webisodes from the UK at the time (bah).I believe they wrapped up some of the mysteriously disappeared characters (i'm looking at you, Ali Larter!) and capped some of the storylines.
Much like how Buffy, Faith and Angel all are still ongoing Comic series and i believe firefly had a bunch of comics too.
