I just blasted the hub with another shot of PB Blaster and will be giving it another shot. The repair manual lists the two bolts holding the caliper on the knuckle as "non-reusable part." Why does this say this and should I really buy new bolts? What is the common practice here?

if a bolt or nut is listed as non reusable, and it holding something critical on the vehicle, it's a good idea not to re use it...

So let me try and understand this, the risk is that the bolt could fail simply because its been installed more than once??

I don't have all the info on that particular bolt, but most of the time when a bolt is a one time use bolt it is because the torque spec on it actually stretches the bolt just a little... this stretch is what causes fasteners to fail if they have been retorqued to the same as originally caused them to stretch... you should never re use most head bolts because of this, flywheel bolts, and a few other fasteners are typically one time use as well... another common issue when a bolt has been stretched is that it can never be torqued properly, thus it can come loose in certain circumstances...

Does anyone have any pics to remove the front calipers? Or let me know what bolts or screws need to be removed after the pads are taken out.

Thanks
