Not mine, I don't have enough gear to seriously try this one, but a complete and very detailed guide. It is specially tailored for protection paladins but full of tips readily usable as a holy paladin. just go read Rhidach's blog post on How to defeat heroic 10man Trial of the Crusader.
I seriously point you to this one, there are so many tips for a paladin that I didn't think of (not playing prot enough these days) I'm ashamed of my gameplay :P
Thanks a bunch Rhidach :)
Update note 20th November: I've compiled a more complete list, including Rhidach's guide, you can find it on Trial of the Grand Crusader (ToC Hard), Guides & Tips Collection
