Did you change the "Outside color" back to white ( or at the very least something far less saturated because with that shader a little goes a long way) and then change the "Col" to blue? Just putting that out there in case you don't want the glass to look as saturated as it does at the moment. As far as the MR lights, hey go for it, but to be honest I don't know if anyone uses say the mib point, spot and infinite lights instead of the regular Maya ones.
