Vapour barrier to concrete wall


Based on what I've read, I'm supposed to place a vapour barrier to the concrete wall according to
(I'm in southern Ontario).

My questions are pretty simple

1. How do I attach the vapour barrier to the concrete? Should I be using acoustic caulking or somehow nailing/screwing the barrier to the concrete?

2. Do I apply whatever technique in 1. to the bottom edge (where the floor meets the wall) to create a perfect crease?

3. Does the vapour barrier have to start only at the group level rather than all the way to the top?

4. Seems like a LOT of insulation to put a set horizontally and then vertically between the studs. Is this really necessary?

I like to staple it to the sill plate and just let it hang. It will be on the floor so just set the P/T 2x bottom plate right on top of it. check code up there . Here we just put a R13 in the studs upright.
