What on earth is all this %20 crap at the end of the GUID? (newfs?)

Not that unusual at all.  In ATA and SCSI alike it's common for text
fields to be defined as fixed length strings.  I've seen many vendors
pad their entries out with spaces; for some reason they're allergic to
using NULLs.  geom should probably be modified to strip trailing
whitespace from the serial number.
