Replying to Quiver Killers

I'm looking to buy some quiver killers for my Jeronimos and blue steeles. I broke a jeronimo, and am planning to fix it, but I'd rather not use it in the park in the future for fear of breaking it further.
I have a pair of FKS 140s currently on the Jmos, and the steeles are already drilled for that binding and my BSL. How difficult is installing the inserts? I'm somewhat mechanically inclined, and I have a small drill press as well as a usable shop area, but I don't want to wreck my skis. Is it something I should ask my local shop to do?
Also, what are the differences between QKs and bindingfreedom?
