A good start lil Brother...I would add a bit more to the scripts on the various units under the fluff...and not worry about tactics on independant units...
State, in detail, what their primary functions are in the chapter and a few minor notes...use the dex as more or less a format and bring what you know of the Brother's Grey to this...
It's meant for us to not only be as accurate as we can but to be able to throw a little of ourselves into it...
Also there are twelve Wolf Lords...you still have to include the Great Wolf, as besides being the chapter master he is still a Wolf Lord in his own right with packs to lead into battle....
We will worry about the Grammar and punctuation once we get it all laid out...
If you can send it to me in a PM and will make some additions to what you have...
for instance...where you say that the Venerable dreads are ancient warriors who have suffered grievous wounds and been granted the ability to continue fighting for the Emperor...you forgot to say how they were given this priveledge...'Interned in ancient suits of Dreadnought armour, connected to life support systems which allowed them to continue in their glorious fight for the Imperium of man'
