Yes you can go back at a later stage and no, the ropes only have a scripted use.
So how can I get back without going through the maze? I forgot the sulfer!
Also, if I have to actually fight any DeathKnights to get out of this place, I'm probably screwed. I'm level 10 now, but haven't gotten the Level 3 Battlefield key yet. I've been avoiding DK's cause they're just too tough right now.
Any help is appreciated.

Michael
