How to catch up for 5.2 -
Run heroics for 463 gear.
Run random scenarios in order to get:

Contains some 450 items, but it's mostly heroics (463) and more importantly some EPICS (476).
Do all of Townlong and Dread Waste non-daily quests. You'll hit Honored with Shado-Pan and Klaxxi and you'll gain access to VP cloak and neck. Assuming you have full 463 + two 489 pieces, brings you up to 466.5.
You'll need a minimum of four (4) 476 pieces to reach 470. If you manage to do Sha of Anger, you only need 3 pieces from LFR. I'll explain later.
What can you do?
- LFR. It only needs 460 to do the MSV
- Sha of Anger. Even if you don't get anything, the first time will drop a quest item that you can turn in for FREE 476 boots.
- Random scenarios still have a chance to reward 476 epics from their treasure chest.
- You could also play the AH if you've got the gold
I also suggest doing Shieldwall dailies (or the Horde equivalent). The dailies are easy, the grind isn't hard and at honored you can buy a 496 ring with VP.
Moreover, you can find a group to do the rare spawns who drop PVP trinkets which are 483.
So - once you hit 470, continue doing what you're doing until you hit 480. Hit exalted with Shieldwall (or Horde equivalent) since their VP items are 496 while the others are 489.
Once you hit 480, you are set to do LFR for Throne of Thunder when 5.2 hits.
Out of all the factions that exist in Pandaria, you only need to really grind one and it's not even a grind. You can see that the reduced VP cost is pretty helpful in reaching your goal of 480.
