I think you should know the central construction, it's simple enough (half of Hutter's "gentle introduction" would suffice). But at least read some good textbooks (such as AIMA) that give you overview of the field before charting exploration of primary literature (not sure if you mentioned before what's your current background).
I own a copy of AIMA, though I admittedly haven't read it from cover to cover. I did an independent study learning/coding some basic AI stuff about a year ago, the professor introduced me to AIMA.

It's a bit difficult to summarize. Is sort of did so here, but I didn't include a lot of detail.
I suppose I could try to hit a few specifics; I was jumping around The Handbook of Brain Theory and Neural Networks for a bit, I picked up the overviews and read a few of the articles, but haven't really...
I searched the posts but didn't find a great deal of relevant information. Has anyone taken a serious crack at it, preferably someone who would like to share their thoughts? Is the material worthwhile? Are there any dubious portions or any sections one might want to avoid reading (either due to bad ideas or for time saving reasons)? I'm considering investing a chunk of time into investigating Legg's work so any feedback would be much appreciated, and it seems likely that there might be others who would like some perspective on it as well.
