Agreed with pineteam. With regards to temperature compensation, unless your airline has the optional FMS landing system approach (FLS approach) installed, the approach is not compensated for cold (or hot!) weather. The chart usually specify a minimum temperature for using LNAV/VNAV minima. If the temperature is below that value, you can fly the approach using corrected LNAV minima and an adjusted vertical path, using NAV and FPA to fly it. Hopefully this helps.
