You have to get the task from Headmaster Ambrose to get to Krokotopia.

You go to Marylebone after you finish Krokotopia and Krokosphinx.
Yes you can go back. There is a door in the ravenwood tree that let's you go to different worlds.
Yes you can.
you don't have to be a certain level to go to Krokotopia. But i would recommend you to be at level 13, 14, 15, or 16. i was at level 15 when i started Krokotopia. TALON SPIRITFLAME DEATH LEVEL 60 LEGENDARY CURRENTLY IN ZAFARIA
Once you are ready to go off to Krokotopia, Professor Ambrose will give you a key and ask you to enter.
To get to the Oasis you must be able to go to Krokotopia. To get to Krokotopia you need to have done the quest that enables you to go (which you get from Ambrose) then while in Ravenwood go inside Bartelby's mouth then to the door in the middle of the room. After that click on the door then on the Krokotopia sign. That should take you to the world door in Krokotopia, after that run up the ramp through the normal door and you are now in the Oasis.
