i hope this helps,
I already tore one down, a 1957 bathroom, maybe this might give you some insight, I mover a wall 13 inches back to make a shower /bathroom, I in the middle of framing it. but the tear out took me a little over a 2 weekends, I am only doing this on my free time.

and here is the shutterfly link my wife posted the pictures on.

the framing was not a load bearing wall, you need to assess whether the wall is load bearing, in general, if the wall runs perpendicular to the joists (cross ways) then there is a good chance that the joists are resting on the wall, but is the wall runs parallel to the joists, and it is located between joists, then it is not load bearing.
but you need to know! 100%
otherwise you need to support the joists when you are removing the wall.
you can still move load-bearing walls as long as you support the joists adequately
the tile was set in steel mesh with like 2 inches of concrete and then thinset then tile.
i used a pick to pull the tile off the wall in big chunks
oh and the waste it generates it big, i filled up a 15 yard roll off with an 80 sq ft bathroom and wall.
when i tore out the bathroom, i removed the entire thing, makes it easier to fix problems that you may not notice.
and drywall is cheap
