Okay, this wikipedia article is really good:
http://en.wikipedia.org/wiki/Prothallus
And helped me with a lot of what I was struggling with.
Basically it tells exactly how a fern gametophyte (prothallus) works.
I have some fern spores that I definitely want to see if I can get them to germinate and watch for the little prothallus to come up.
