first of all why do you wish to change your crankset? if you are looking to change your gearing it may be easier to change the chainwheels on your current ones.
more often then not changing crankset requires changing the bottom bracket aswell. all cranks are designed to work with a spefic lenght spindle. sometimes changing from a shimano 105 to a 600 of approximatly the same year you do not need to. going from what you have to a Triomphe crank will most certainly require you to do so.
116BCD refers to how far apart the chainwheel bolts are. most shimano road (non compact) are 130BCD, Campi 135BCD
9/16x20 refers to the threading for the pedals (this size is pretty standard these days but when Triomphe was made some cranks still came in french threading)
