I am thinking of pulling up the wall to wall carpet from the living
room in my apt. ...what is involved...

What kind of flooring is under the carpet? If oak, could be stained
from previous owners. The padding could be stuck to the wood in
places. There could be many nail holes in the floor from previous
installations of carpet. The padding could be randomly stapled to the
floor. You could be getting in to a bag of worms. Peel off a corner
and investigate what is underneath, and you will have a better idea of
where to go from there.
