The problem with playing on MU* derived from book series is that you must have read the series in question.
With this particular game it's really not a necessity; the basics are linked above, and it's really easy to pick up on. It's basically low-fantasy idealized France with angels and 'love as thou wilt' being the religious base. So for your own comfort level you might need to read the books, but plenty of folks do just fine. It helps that people are really mellow about letting you know something major (or just letting it roll off their back because pretendy fun time).
@Huzuruth My first advice would be don't, but beyond that (as @Echx has said), speak to staff about it, and most certainly play a diplomat of some sort, or at least someone along those lines.
Playing a commoner from Terre d'Ange is not recommended; playing one from elsewhere (there are a lot of xenophobic d'Angelines) is REALLY not going to net you a whole bunch of RP. I mean you'll get into the public at the inn scenes, but getting in on the plots and such would be difficult. Plus, going that route doesn't connect you to any other characters, which is one of the better ways of getting involved. I mean it can be done, but the hoops and the work would be a little daunting to a new person trying to get their foot in the door. It ends up being an entirely different game playing a character of this sort, and it's not necessarily an improvement.
ETA: Any basic concept you want to play can generally be shoehorned into a character type that will be able to get involved in things. I know staff will never tell you you CAN'T do a concept like this there, but they do generally recommend against it. Still, if you're really super interested and your heart is set, I imagine it could be done.
