carbon fibre roof weight ?

No idea but I know that my carbon fibre STI6 spoiler is a LOT heavier then the previous GRP one. That may be due to it being "cheap" carbon fibre (£300 rather then the £600 I could have paid).
I bet it is marginal and more for looks and bragging rights then any real saving. A carbon prop shaft would be a better performance increase as its rotational weight. Also light weight flywheel and pulleys and battery etc.

There is a debate as to whether lightweight pulleys are actually benefitial on Subaru engines, as the have been rumoured to have caused damage.
How much is a lightweight prop? I'm guessing it'll be doube the price of a roof

The newage roof is very heavy apparently, and as it's a weight saving from the highest point of the car you 'should' get most benefit.

Not sure how on earth lightweight pulleys could cause damage??? I have had mine for 6 years and all good. I wouldn't have thought somebody like RCM would manufacture them if they were known to be an issue. If anything I would have thought they reduce the chance of damage as the standard dampened crank aux pulley can fall apart with age.
I have no idea on the prices. Probably pretty expensive but would make far more difference performance wise then the roof I would have thought. Of course the roof is going to be handling too if its really that much lighter.

There was a discussion about pulleys on here a couple of weeks ago. Something to do with the rubber damper in the standard ones not being present in lightweight versions
