Update:

went to run Ramps and got the message "you must be lvl 57 to enter this instance"

so much for trusting the data on wowhead.. said you could access at 55.

trudged back to the "real world" and did 2x runs of Upper and Lower Blackrock Spire (as the quests had now opened up)

I had set my hearth already to Honor Hold, so once i hit 57 I could hearth back to Outlands.

did a quick run of Ramps before having to call it a day..
