for the loot situation you could always level with someone else in your guild or charge someone for being there and have them loot everything that isnt bop.

i did this when i was leveling my last toon would charge 10-15 g per run and i had a regular who towards the end would just help out my toon when i didnt feel like 2 boxing.

on runs with a 70 all you should care about is Boe blues and bop upgrades. Cloth and stuff like that if needed for professions/first aid everything else just leave.
