Help on replacement crankset!

[MR-U]

Hi Guys

Just brought a Specialized Rockhopper 2012 (A*) off ebay, only to find that the pedal on the right hand side, attached to the crank, was cross threaded and has completely threaded the Crank arm.
Could someone please tell me if the crank in the link below (B*) would fit my bike or if not, could tell me what would please?
I've been searching for some time but I am getting stumped at not knowing if I need a Square or Octalink fitting.

I hope this makes sense to people, as I am just going around in circles trying to find out.

Thanks for your time!

In link A* it says: "Bottom Bracket: Shimano, Octalink spline, cartridge bearing, 73mm" under product details.

So the set in B* will not work, unless you also install a new BB.
