If any additional dates are required, these have been quoted from "The Allocation History of BR Diesels and Electrics - Part 3", compiled by Roger Harris, which takes the loco up to the end of its active service with EWS:
Numbers:
D1973: 11/1965 - 09/1974
47272: 09/1974 - 09/08/83
47593: 09/08/83 - 03/08/91 Renumbered as fitted with electric train supply
47673: 03/08/91 - 16/12/94 Renumbered as one of 7 locos (47671 - 677) fitted with, as mentioned, increased ETS of 75 for working sleeper trains on the Highland main line
47790: 16/12/94 - Present
Depots:
Haymarket: 11/65 - 09/83 (Spent a year working from Gateshead in 1968/69)
Eastfield: 09/83 - 03/91
Inverness: 03/91 - 04/94
Crewe Diesel: 04/94 - 11/97 (Also seems to have spent some time at Bristol Bath Road during 1993)
Motherwell: 11/97 - 06/02
Crewe Diesel: 06/02 - 01/04.
Stored at Healey Mills on 01/04/2004.
Names:
"Galloway Princess": 16/09/83 - 03/1994 (Named in a ceremony at Stranrear station, name removed at Bounds Green TMD)
"York Intercity Control": 22/03/94 - 09/1994 (Named in a ceremony at York Station, name removed at Crewe Diesel)
"Saint David/Dewi Sant": 01/03/95 - 12/2002 (Named in a ceremony at Swansea station, name removed at Crewe Diesel)
I think that the renumbering back to 47593 for the (re)naming ceremony was temporary and purely sentimental: The main difference between the Railnet dedicated 47/7s and (most of) the 47/4s was that the latter were fitted with RCH jumper cables, for working with propelling control vehicles, and twin fuel tanks (The later 47/4s, and scattered other examples, also featured twin fuel tanks, which gave rise to the "47/8" sub-class).
I would suggest that the following webpage would be of considerable value:

As for multiple working, I thought some 47's had TDM which would be compatible with class 47's? Presumably DRS's don't? And why do the 47's require two drivers per train?
The push-pull 47/7s (47701 - 717) used Frequency Division Multiplex, a less sophisticated version of TDM, when altered to work with newly converted DBSOs on the Edinburgh to Glasgow services. The DBSOs were modified to use Time Division Multiplex when they were transferred to the GEML to work with class 86s, so would no longer be compatible with those 47/7s. As
TheEdge says, in general the 47s are not fitted with any multiple working system.
