Okay, I feel like a noob, but what is TMB?  The only thing about KID is white is not obliged to play 2.c4 when black, if he carries through with typical KID play, may end up in the Pirc or something else entirely.  Should I pair the Pirc and KID together as a system against 1.d4?

Do you like the Grünfeld? Avrukh's GM Repertoire book will be released soon.

In that case you could start with an intro book (for example Rowson's old book, or maybe there's something newer) which explains the plans and then use Avrukh to bring you up-to-date.

Fluffy's two King's Indian books are an alternative (haven't seen the yet). Or his excellent Play the Semi-Slav (needs an update due to age).
The other KI book, by Bologan, is also great. It's a year or two older though, but I like his writing style a lot.

edit: In all cases you'll need another book for garbage collection (white avoids c4).
