Recommended path for dailies & rep grind?

[MiRai]

If you come across the Dark Soil for Tiller friends, read the tool tips and give them to one of the two on the item, you'll gain a lot more rep with them than someone that it does not mention. Once you hit Best Friend with someone (exalted) you can't turn them into that person anymore, so use them on someone else till you no longer need them. They are BoP, so watch which toon digs them up.

Just a quick correction - All of the items you dig up from the Dark Soil around Pandaria tell you exactly who you should give it to in the tooltip in order to receive extra "friendship". I would personally not spend my time trying too hard to find these things because none of these NPCs do anything special for you once you become "best friends" -- All they do is give aesthetic changes to the look/feel of your farm.

EDIT: It was apparently too early in the morning for me to reading threads...
