I'm new to writing kernel drivers, so I'm trying to get a better grasp

For example, if I was trying to write an application that interacted
with a Palm or some other handheld device that connects via USB,
should I be looking into kernel extensions or using a driver interface
based on the USB family?
A good question. There is a document addressing this topic you may find

To your direct question, you would not need any kernel code to
communicate with such a USB device.
