Yeah, hirelings wouldn't get specialization. It's something you need to have levels in fighter for, which 0-level men-at-arms technically don't.
Henchmen get XP at half shares. I've seen debates as to whether or not they are supposed to count as a full share when dividing experience but only 50% is applied to their character sheet, or whether it's always a half share and none is "lost".
I count it as always a half share. So when XP time comes, if there were 3 PCs and 2 henchmen in the group I would essentially double count PCs and then double their share. So let's say that there was 8,000 XP earned. I would divide that by 8 (3 PCsx2 and 2 hench x1) to get a base share of 1,000 xp and then award 1,000 xp to the hench and 2,000 to the PCs.
