simple answer: higher the spring rate..the stiffer the spring

complex: Spring rate : Usually expressed in lbs/in, it’s the force required to compress a linear spring one inch. Linear springs have a constant spring rate. Progressive springs have progressive spring rate that rise has the spring load increase.

you are right. metric is to import as Standard is to domestic. thus if made over seas, expect metric measurements; if made in the states expect it to be Standard measurements.
now to answer your Q about the diff suspension sets, the 11kg springs would suit an oversteer (drift) set up better than a flat steering; also they would function well in a drag set up. the 7kg all around would be good for road racing or throttle heavy auto cross.
