So, in the defautly flight I've now got the Master Avionics ON and it set to GPS.

That seems really strange airbumps. I would expect that you need to have the NAV/GPS Switch set to NAV mode (not GPS mode) to get it to follow the ILS and G/S.

You can load an FSX Flight Planner plan into the CDU so that the FMC will follow it in NAV mode. It would act just like the A/P in the default 737-800 following that same plan set in GPS mode.
