Some basic reading of popular sources (after enjoying some trash fiction about the period) formed this question in my mind, but I'd prefer a digest rather than a heavy textbook....
I'm currently reading "In search of the Dark Ages" By Michael Wood, it covers English history from Boudicca's revolt to the Norman conquest, and about 20% of the books is on Alfred, while it of course also talks about his wars with the Vikings it also does contain information about his reforms to education and administration. It's very readable and Michael Wood writes very well. I would recommend that as a starting place.
Well, I can't help with overview or survey literature, but when you feel like progressing into the heavier stuff David Pratt's The Political Thought of King Alfred the Great, (Cambridge, 2007) is an excellent and comprehensive study.
