For Printing you need a completely dark room. However for just film developing, you can use a change bag and a tent, I also recomend powderless disposable gloves for handling the film in the bag...trust me on this one.

As for colour film, you can do that just as easy as b/w these days. Yes, you need to watch the temperatures much closer, but if you get a Tetnal or Unicolour kit from Freestyle or B&H it's a simple three step process, just like B&W.
