The Profile crank arms you linked will not work with your bike unless you change the bottom bracket. Your current bottom bracket (the axle that runs through the frame that the pedals connect to) is an 8 spline and Profile cranks are 48 spline. To run the Profile cranks you would need to change the bottom bracket spindle.

The linked crank arms are also overkill for someone your size, I ride that type of crank but I am 6'6" 230lbs, you should not have any problem with a light set of cranks.

Your best bet is to ask the shop what the options are for getting shorter cranks, they should be able to let you know what would be compatible or be able to order something in for you. If you want to do it yourself the cheapest route is probably to replace the bottom bracket with an inexpensive square taper or ISIS, your bike has what is referred to as a Euro style bottom bracket, this is a common and easily replaced piece. By going to a more common bottom bracket you will have more options for cranks. Something like Sinz Expert cranks would do for a rider your size and chainrings for them are cheap and easy to change.
