Basement Finishing Advice
#1

I'm in the process of finishing my basement. The HVAC system has been installed and the electrical work will be complete soon. I plan to do the drywall, suspended ceiling, etc. myself.
The questions I have are in regards to finishing the outside walls. Most all poured conrete walls floor to ceiling. A couple are poured concrete for the lower 1/2 and wood framing (2 x 6 w/ faced insulation) on the upper 1/2. These walls have about 2-1/2" of offset due to differences in width of the concrete and framed sections.
I plan to build 2 x 4 framed walls (floor to ceiling) against the outside walls in both situations. Should I use pressure treated studs for these walls or use only pressure treated lumber for the floor plates?
In regards to insulation and vapor barrier, should I insulate the floor to ceiling concrete walls and the 1/2 concrete portions? If yes, do I use faced insulation or rigid foam? Should I install a vapor barrier? What kind? Should the vapor barrier be placed against the concrete prior to insulation or between the framing and drywall?
Thanks in advance for your advice!

I would use the treated lumber for your bottom plate only! Your vapor barrier goes between the drywall and studs. If you use faced insulation that is your vapor barrier. If you use unfaced you would use a 4 mil. polyethylene vapor barrier. When framing your walls I would hold my framing 1 inch away from the outside walls to prevent any possible moisture transfer.
