Although no individual sense could replace sight, especially when it comes to archery, but a combination of heightened scent, hearing, from those large highly placed ears, which are used by many animals to locate the source of noises, and the vibrations in the floor, could pretty much pin point a target, especially in an enviorment that is nearly hermetically sealed from the outside world, add a little bit of magic to that, and you've got a pretty sure shot.

But for the other things, you've got a point. I don't understand how you could put up a tent, or assemble a master level lock with no eyesight. Falmer, also, live in some of the most architecturally dangerous places in all of Skyrim (Seriously, what was the Dwemer's problem with guard rails?), and as you said "You can't hear a cliff" or a booby trap, or narrow walk way over a 10 story drop.
