What is the difference between amount and radius?

Amount controls how much sharpening is applied. Radius controls how many pixels around each edge are affected. Smaller radius sharpens fine details, larger radius affects broader areas.

Should I sharpen before or after resizing?

Sharpen after resizing. Resizing can soften the image, and applying sharpening last gives the best result.
