I only dual box, but I do all quests -collection included. I figure, I'm loosing a little xp for having a second toon along, so I make up for it with these quests that I kinda refer to as "grinding quests".
I do some collection quests. I have two 70s I leveled questing (individually) so I sort of know which gathering quests take a long time. But generally, if they ask me to gather more than 5 I skip. Exceptions both way if I remember droprate being particularly good or bad.

For my 5x Shamans, I'm now up to 56, I did:
1-20 Questing in Draenei starting area (did most drop quests)
20-40 Boosted through SM Cath Ad Nauseum
40+ Have been questing (avoiding 5+ gather quests), and doing instances by myself (not boosted). So far I've completed ZF, Ulda, and at least attempted ST, BRD
