I think this should help. It is in the same datasheet. It seems they still have some errors with the old names.
Revision D (June 2009)
This revision includes minor typographical and
formatting changes throughout the data sheet text.
Global changes include:
• Changed all instances of OSCI to OSC1 and
OSCO to OSC2
• Changed all instances of PGCx/EMUCx and
PGDx/EMUDx (where x = 1, 2, or 3) to PGECx
and PGEDx
As for the programming pinouts -yes you are right in your icsp connections - don't forget to select which pair you are using in the Config statement.
Sure you will have seen it, but this is a very good Pic24 tutorial with hardware and software, have done all the experiments but yet to prove the Ethernet one, bit beyond me on the pc side.
