I did Ramparts 55-60. One clear of it takes 15-20 mins and gives a full level with RAF. It can be cleared in 3-4 pulls.
1st pull go up to the guy who calls the dogs.
2nd pull go all the way to the spiral including the 1st boss.
3rd pull clear hallway and open area before the last 2 bosses.
I also kill Omar for lewts.

The greens in here are a good place to start gearing your characters for questing.

I got all the gear with gem slots from the lower 60 instances. They are way OP if you gem new WotLK gems into them. 24 stam gems only cost about 7g each on my server. I had ~15k hp on my pally tank at level 66.

Maybe I'll fraps it this weekend as I still have locks that can get xp in there.
