One suggestion I have is to only talk about UI and mechanics when they are relevant to what you are doing. For example, I don't think it was worth trying to explain the empty Transfers screen. It isn't particularly interesting when nothing is there; and viewers will probably forget what you said about it by the time you actually want to use it.
I guess different people like to see different things in a LP video; but I'd personally prefer when players get into the action quickly, and play essentially how they normally would - explaining things as they come up. If there are some interesting bits of game mechanics or UI, there will be plenty of opportunity to talk about it when it is time to use them.

If you're looking for soldier names, I choose Lydia Bennett. Make her a melee attacker (if you intend to use melee). She's a very forward person, and somewhat reckless. (But don't get her killed! :p )
