I'm a new multi-boxer as well and have used this guide to help run my current tri-boxing team. I'd check it out as it is streamlined for RAF Horde questing (no collection quests, only kill quests, etc):
Horde and Alliance Multi Boxing RAF 1-60 Leveling Guide

Some people have been able to go from 1-60 in under 2 days using this guide. My time will probably be closer to 2 days 14 hours /played, but it's still a very good guide.
