Brute is a decent DoT tank, also for outlands. The thing about leveling heroes you don’t use often is that you need the resources for it. If you have money to spend (i finish Hard Crusade every day, so i have plenty of gold to lvl 15 champs), level them, if not, don’t. The closer you get to lvl 65-70, money will be less of a problem and it's replaced with a lack of exp potions (at least for me). I suggest you look in to the Outland/Guild Raid guides to see what you should level when you have resources left.
As for what skills to focus on. Chaplain's heal is the most important, Convert is a good 2nd. Inviolability is nice against AS teams, since it lets her tank AS for a bit. Pilum is the least important when we talk about Chaplain. But personally, i max all skills on all champions (15) i level.
Hope this helps!
