There are summaries for each episode on the wiki, and I also had two episodes for the S1 recap in my podcast feed (trough MediaMonkey).
Basically, they consisted of all important phrases said in the episodes stitched together. It worked, but wasn't very easy on the ears - a lot of information in a short time, and rapid changes in mood. Hence why I prefer the summaries or just listening once more too things I can't recall.

A map would be great, but on the other hand probably pretty hard to compile. Not always do they give explanations about which way they're traveling and everything.
