I don't think there's a piece of material that's all these, but I played the Pirc a while back, and here are my thoughts on some stuff that's out now:
Pirc Alert! - Silly title, but great for some coverage of variations, and has an enormous section on the different Pirc structures, piece placements, pawn breaks, plans, etc...Great for that. As said, some crosschecking them with Vigus' book. This reminds me that I should take the Pirc up again.
I have both these books and agree with the recommendations. Pirc alert settles you comfortably into the first few moves covering the ideas for both sides...particularly good for whites 4th move. It also taught be a couple of valuable lessons about openings I found it less clear/easy to use once past these early stages.
(The lessons were...don't spend all your time studying openings and don't expect an opening to give you a winning advantage...more likely as black that good opening play will get you equality or or slightly better or slightly worse ...and get you into the set up that you like to play.)
The Pirc in Black and White is really impressive in it's scope and therefore you might find it a little dense at first sight...but it's surprisingly digestible if you give it a chance..and it's comprehensive - the authors first I think and clearly a labour of love.
GM Nigel Davies has done one of those Fritz training cd's too where he sits and chats you through it all.
And finally there is "Starting Out: the pirc/modern by Joe Gallagher...not a book I've personally warmed to but I've not delved into it enough to give it a fair judgment...it has the starting out format that I appreciate but I think irritates some more advanced players.
A note you might find useful in the pirc is:
3.f3 ... is almost an anti-pirc move and worth having an idea what to play against it as 3...g6, 4.c4 takes you into the Samisch Kings Indian - not a prob if you happen to know it - and the alternative seems to be the odd looking 3...d5
...also I know motowndave who used to play here and was rated over 2000 played the pirc almost exclusively so you might want to look up his games for some practical examples.
