Please help me upgrade my 90s Colnago Superissimo's drivetrain to cassette.

I intend to pair a campy c-record 8 speed hubset (like this) with a c-record rear derailleur (like this) through C-record ergo brake/shifters (like so).

Am I right to presume this should work? What cassette/chain combo is best that won't wear out very rapidly?
