"Inherited" Bike... Lots of questions
A better approach to deciding is to figure out what wheel as a whole you could get for your money, by 


Buying factory pre-built (e.g. from Mavic or DT Swiss)
Buying custom built wheels with a choice of components from stores such as www.wheelbuilder.com, or using a local wheelbuilder
Custom built by local wheelbuilder using the Chris King hubs, you get to choose rim and spokes.


With the last option you are not paying for new hubs, but you will have to pay for the wheel to be built up.
