Community central has some resources on templates in general and infoboxes specifically. I've probably learned most about templates by just opening up existing ones and looking at the code though.

But looking at that infobox, the main issue was that the values weren't correctly labelled. Entering | Episode = One wasn't doing anything because it was looking for | episode: = One I went in and tweaked it so the info is showing up now though.
