Just a FYI, and not really meant for argument or debate... took a while since I've been very busy IRL... but...
A person at TFF plus my own checking yielded where I can get at everything manga and sound stage related on-line. Aquired all of it and been plowing through it in what little free time I've had.
Read the Magical Girl Lyrical Nanoha Sound Stages through to 2-4 or 2-M if you prefer. Also read the manga for A.
I'll be starting the StrikerS manga shortly, then read those sound stages that apply to it some time afterward (3-1 through to 3.8 or so).
Hmmm... pretty sure I've been lead on a snipe hunt, at least so far... the manga to me at least does not have a much brighter outlook on it than that given by just the anime. I'm not seeing it so far, and in fact find at several points it seems to contradict itself. And Graham at least is barely even mentioned in any of it for either A's manga or the Sound Stages through A's. There may be more though in StrikerS and beyond. Oh well.
I've been taking plenty notes though.
