As pinotnoir says, I'd just grind to Honored rep with CE and HH in instances. Assuming you're boosting with a 70 Paladin then you should have NP as all of Ramps is soloable, so you can at least clear trash to 1st/2nd boss no matter how bad the 70's gear is. You'll be 60+ easily, then do a bit of research on HFP and Zangar quests and knock the ones that give you gear to fill some slots. Then maybe fill out some more gear slots with crafted or AH'd BoEs. This will be more than enough gear to do all the rest of the HFP/Zangar quests even without a 70 helping,which should get you a complete set of gear if you do everything and choose the rewards correctly.
