If each code represents halo.track.letter (example: 24.01.1 would be "H"), then things seem a bit too easy because, hey, we automatically know every code, from 24.01.1 to 24.16.8. There may be another step. Currently, there are graphics on [http://yearzero.nin.com yearzero.nin.com] that appear a bit weird, so to speak. Off to the left there is some noise, and around the track "My Violent Heart" there is an odd pattern. These exact same graphics are found on churchofplano.com. Since 24.10.2 is the only code on there, it's reasonable to suspect that O (the letter that 24.10.2 goes with) is the first letter in the puzzle. The next site to use these graphics will be the next letter, and so on.
Thus far the corresponding letters to the entries, in order, given on this site, are "surgodgiventanoinw". The phrase "god given" is clearly readable in the message. As other clues are found and other letters are derived, perhaps a clearer message will emerge.
At the very least, it gives a definite scope of the number of clues which may exist, assuming there is a number for each clue.
Another theory corresponds to the first, where numbers stand for clues so as to keep the fans deciphering on track. Since there are so many letters to fill in, it's possible that we are left with a few at the end. It could be that the letters ''left over'' would be the anagram.
