I actually use the Battlemaster trinket myself, I just hadn't put it in the guide since the passive +heal trinket section is a link to a wowhead search and not a list. About the Nightseye vs. Shadow Pearl discussion: in terms of mana regeneration, Nightseye is almost always better than Shadow Pearl on live right now, even if you innervate yourself. The only reason (on live) to go with the spirit gem is if you really want the +1 healing on your aura, but it's probably not worth it.
The way things are looking on the PTR, Shadow Pearl may be a better gem. It's slightly worse in terms of mana regen if you don't innervate yourself, but a decent amount better if you do, and it's close enough that the bonus to the aura may mean something. However you really want to go for
[Royal Tanzanite], which is not unique anymore on the PTR. You may be interested in reading
