Sorry, that the manual does not describe everything clear enough.

Yes. But Geoff should use f STO 1 and RCL 1 in the program instead, then R0 is still free to use as index register.

No, this is true only when you are in GPS menu, not during regular calculation mode.

Yes, because your temporary value will be overwritten every second. Perhaps you think that f STO n enables continuous update generally to all registers? No, f STO n enables continuous update only for the value, which is actually displayed. You can choose which value will be updated individually.

There are 8 different GPS data available, but you can choose which of them are continuously updated and to which register it is written, the other registers are still available for your calculations.

This would be required only if you want to use all eight GPS values (UTC time, latitude, longitude, Speed, Heading, Elevation, doHP and No of Satellites) to be dynamically updated. But I don't think you need all of them. At least the HP-29E could be extended to use also registers 8-9 in a later version.

That's one small step for a man - one giant leap for mankind.
