Am I reading correctly that the 1540 sends data faster

By default, yes. Either drive can do serial bus transfers at either
speed.
This brings up the obvious question, can you
'downgrade' a 1541 to a
1540! :-)
Yes, either temporarily by using the "UI-" command, or
permanently by
replacing the ROM. Other than the ROM contents, the hardware is
functionally identical.
