One of the easiest fastest ways to gear anyone, for pvp anyhow, seemed to be the pvp building in your garrison coupled with running ashran. This building would drop gear/honor/conquest very often... pretty much for free. But, even just running ashran you will get honor geared quick.
Yeah, it is. Try stocking up some trashran artifacts as well. On patch day buy as many pieces as you can afford then proceed to do events and artifact farm and you should have full gear within the day.
Also pay a visit to the new version of Doom lord Kazzak, he drops 705 ilvl stuff which you can use until you replace everything else first.
