It is worth it. You get good expierience and the dragon gem + a skill point in boomerang for free (warriorsguild)
The holy itemsquest is a hard to complete quest. It is worth it if you get the item you want. (maybe trying to reload till you get it).
The dragon armor gives you a skill point in elemantal hail (IIRC) an temporarly bless. That if you have all components of it. Then you can throw away all you want.
But remeber, if you ring the gong, you cant come back!!
