On Question #1, yes, use the .inv file and look for the needed variable ID. Never assume that a given field will always be in the same position in a GRIB file with lots of fields. This principle is true for all NCEP models, not just the RUC.
On Question #2, as you now know, CAPE/CIN in the RUC (and NAM and GFS) currently do not use *virtual* temperature in the calculation. NCEP is considering making this modification in the future, and it will be discussed in a much wider forum before making such a change.
