You can install an addon called Lootfilter. Donwload: http://www.lootfilter.com/ You can sort out the items you doesn't want.
I currently have WoWmatrix and it still updates all my addons. It does goto curse to get the updates though.
Lootfilter is great. Except it seems that HB doesnt recognize that something was deleted. So if you loot eg. 60 different items, and lootfilter deletes 55 of them, it will still think you got 60 items in your bags and head to the vendor when it "thinks" your bags is full.
