Lens nomenclature

I'm new to digital Pentax (got an old Ashi Pentax film camera and have been using Canon digital for about 6 years) but I am having trouble understanding the lens nomenclature.

I want to buy some more lenses (probably on eBay or whatever) but I can't distinguish what lenses belong to the 645D (MF format) or the 35mm format

How do I distinguish between the various formats?

Basically check whether or not there's 645 in the lens name- see the lens database for details:
Pentax Reviews - Pentax Lens Reviews & Lens Database

Here's info on the k-mount series:
