the problem with not being 80 is that instead of gold you still receive xp, so all the quest and dailies only give you a small(er) amount of gold.
likewise, your professions won't be maxed and therefore you probably won't have access to the interesting pattern/recipes.

if you're still in outland, i would suggest farming the hell out of it (herb/mine) as those mats can still go for a bit of gold.. other than that i'm not sure.
Maybe the isle of QuelDanas for dailies?
If you don't have Wotlk (and are therefore capped at 70) IQD might be interesting.

I doubt a 70 and 2 66 will easily farm the level 60 raid bosses, but happen to be proven wrong :-)
