Using glued 2" rigid foam(blue) in between the poured concrete wall and my stud framing... Is this correct? Any vapor barrier needed?

Also, do I need to insulate any more than just the rigid foam layer... Do I need to roxul the stud walls?

No vapor barrier per BSC: http://www.buildingscience.com/docu...merica-high-r-foundations-case-study-analysis

Though you may need to control the relative humidity down there, part of the year. Using 16*F http://www.eldoradocountyweather.com/canada/climate2/London.html

http://www.metric-conversions.org/temperature/celsius-to-fahrenheit.htm for your average of three coldest months; Dec.-Feb. with 70*F in room, R-10 and R-15 (Roxul) gives your f.b. inside temp. of 38*F or 31% RH. With R-15/15 = 42*F @ 38%RH.
