Paladin low level dungeon healer tips

I've been playing Paladin pretty succesfully and currently lvl 28.

Ive done deadmines, blackfathom deep and stockades as healer and basically only use my 2 healing spells and purify. I buff the mages/warlocks with BoW and physical attackers with BoM. Lastly I have the armor aura on.

For gear I swap my solo PvE mail for whatever has high INT stats. Whether it's cloth, leather or mail and just heal away when necessary.

Based on my listing above, are there other things I can be doing in 5 man dungeons?
