Hit a curb; chewed up rim and took a chunk out of tire. Will they need replacement?
tl;dr: Sadly, that tire appears to be a goner. The wheel is likely fine, though. You might be able to replace just the one tire.
If you look at the divot cut out of the side of the tire, you'll see ...

Hit a curb; chewed up rim and took a chunk out of tire. Will they need replacement?
Based on your picture I would replace the tire without question. It's not worth the risk. If the sidewall fails while driving it could result in you losing control of the vehicle.

Where is extra fuel consumption in RWD and AWD cars dissipated?
Your premise is wrong. The main reasons FWD cars are more commonplace today are:
easier assembly: the entire drivetrain goes into the chassis as one complete assembly.
unibody construction: FWD cars ...

There is no fundamental reason for RWD to be less fuel efficient than FWD. There are many advantages to FWD, fuel efficiency is not a driver.

Hit a curb; chewed up rim and took a chunk out of tire. Will they need replacement?
Sorry to have to say it, but I think both the tire and rim will need to be replaced. The tire appears to be leaking already, and if it isn't now, then it will in the near future.
The rim could ...

Your mechanic was probably partially correct. The coupling has nothing to do with gears and you may not feel partial degredation in functionality. But I can see ...

Why rear wheels skid at slow, sharp turns when engine gets to operational temp?
