What items from Classic will maintain relevancy in TBC?

I main a rogue, struggling to find a list of "pre-raid BiS" that includes BWL/AQ40/Naxx items potentially.I know things like Scarab Brooch can be used well into TBC, or the KT turn-in trinket for BT, but what else is solid, especially for Rogue?Bonus points if someone can link me a list :)
