Basement Insulation / Vapor Barrier

I've seen several posts on many sites for and against vapor barriers in basements. My basement is all below grade, poured walls (not blocks) and is about 13 years old. The studs are to be about 1/2" from the wall, R13 insulation, then vapor barrier, then 1/2" dry wall.

Is the VB okay? If not, what problems will it cause? Or should I be putting 1/2" foam board on the concrete?

Thanks for the assistance

Id skip the VB. It could hold moisture behind the wall.

And skip the foam on the concrete. It needs to breathe. Personally, I'd skip the insulation, since you are underground and the area is geothermally correct to begin with. The temperature won't vary much more than a few degrees from 70 or so year round. But, since it is there, go for it.

Thanks for the input guys.

Chandler-you don't see any benifits in using the foam? Even as an insurance policy against any possible moisture? My basement isn't wet, I just wanted to take every precaution.

The foam won't stop moisture, so if that is your reason, I wouldn't do it, if no more reason than wasting money. The air space between your concrete wall and the finished framing will allow for air circulation to eliminate moisture.
