Do I waterproof walls first?

Do I put plastic sheeting over the wall?

Can I attach drywall directly over plastic sheeting?

No, don't waste your time and $$ waterproofing the walls. If you have a moisture problem, its a temporary solution at best. What do you do in 5 years when it starts breaking down? The only long term waterproofing is done on the outside. If you don't have a moisture problem, you don't need it.

I recommend building a 2x4 wall instead of using furring strips. A 2x4 wall allows room for electric and plumbing. The question of a vapor barrier in a basement is age-old and has fnantics on all 3 sides. All 3 postions have anecdotal evidence why they're right and the others are wrong. The 3 postions are: vp on the foundation side, vp on room side, and no vp at all.

I put mine on the room (warm side).

furring strips are half the cost and wont make the room shrink by 8 inches, if there is plumbing to be in a wall then go with 2x4 where needed. personal prefrence on the vapor barrier is up to you.

good luck

Another advantage of a 2x4 wall is straightness. Foundations are not flat, but rather have slight bows in them. You won't see them until the drywall is up and painted. Then the wavy walls will drive you nuts!

Also - do insulate the exterior walls. The saving from my heating bills ($40-50/mo for winter months) paid for the it in just a couple of years.
