Is the spring itself considered "unsprung" or "sprung" weight?
Any component that moves as a wheel goes through bump or rebound is unsprung weight. So the springs and dampers are actually both sprung and unsprung weight. The portion of the damper tied to the suspension is unsprung weight because it moves with the wheel. On an FD that means the bodies of the shocks are unsprung and the piston rods in the shocks are sprung. Something like the drive axle on in independent suspension is also both: one end is fixed to the chassis via the diff and one end moves with the suspension.
Just think of the description of the words. "Unsprung" means everything the springs do not support. The weight the springs support is anything tied to the chassis. Anything that is "below" the springs (like the suspension) is unsprung weight.

WTF is springing weight? That is not an engineering term I have ever seen used before.
