Seeing-eye Pokemon!

I would choose...Claydol; because well, basically it has so many eyes: 360 degrees. :3
Plus its part psychic so...maybe it has some telepathy powers to help as well.

I'll say that either Metagross or Arcanine should be my guide.

I can just fly everywhere with Metagross. However, with Arcanine, I can snuggle with him when it's cold and he'll keep me warm.

Well, I think I'd go with Noctowl since he could either carry me flying and in that case the obstacles would be few, or he could guide me on the ground, since his vision in the darkness is perfect and he's quite clever (at least when he rotates his head 180º degrees).

I wouldn't mind going with Metagross either, as it has already been mentioned.
