As to the original question, the type of car, type of driving, weight of vehicle, parts used... all have more of an impact than automatic vs manual.
Yep. On my DD it's about 1200 RPM. It's my first manual with fuel injection. Previously I would push the clutch in and coast. I tried that when I first got this car, and noticed my fuel economy went down.
:agree:
Everyone should learn how to double-clutch.
You don't have to double-clutch to do rev matching. You can release the clutch at the same time as the revs are matched without any additional ware.

On deceleration, a lot of vehicles with fuel injection turn off the injectors when the throttle is closed and the engine is over 1500 - 1900 RPM. The exact RPM varies with manufacturer and engine. Very little fuel will be used on deceleration.

It's a matter of technique, i.e. matching engine speed to gear rather than using the clutch to 'drag' the engine revs up on downshift. In other words, there's no need to wear the clutch at all during downshift (or upshift for that matter on anything but starting from a standstill).
