Don't have time to read all that right now as I have to go have a haircut then train it to London.
But did you mention the creation of the Spartan project? Also I think that Dr.Halsey should count as one of the sub/main characters too, according to the book she has created Cortana in her copy and is responsible for the creations of Spartans.
What I find interesting is there were 6-7 teams of Spartans on Reach, so if they really wanted to milk it they could release their story either as part of DLC or as each separate installment.
Halo Reach Blue, Halo Reach Red etc 
Also, CPT. Keyes? Apparently he was involved in the "recruitment" of children
Disconnect and self destruct, one bullet a time.
