Didn't you just finish Ramps? Outland greens will DE/ Vendor for better results, I'd definitely farm there rather than Scholo/Strat.

Aside from instance farming, pick up trade skills, Mining, Skinning, Herbing. grab EVERYTHING and sell it. Also, invest in bags, if you're ~60 and you're not using 4x 16 slot bags on each toon, you're going to be doing vendor runs, VERY often. Also, loot EVERYTHING, it all sells for something, and you're starting to get into the area where grey weapons vendor ~1g+ and grey gear vendors for about the same. Find an item price addon that shows you how much an item vendors for, I think I use itemvalue. This allows you to pick the highest value quest reward if your toons don't need what is offered and they can vendor it for cash. Mining, Skinning, and Herbing will slow you down, but it's worth it for the cash in the long run. Even if you have to go catch them up to outland levels, go do it. Also, go do as many of the Midsummer Fire quests/extinguishing as you possibly can, each one is pure cash / xp.
