Update #2: I found the LG C8PUA Discrete Codes that I needed.

They were available at:

http://irdb.tk >> Find IR codes for your device >> LG >> Get IR codes >> LG TVs: Protocol NEC1 device 4 subdevice -1

Of course, many of those Pronto codes aren't applicable to the C8, but I do have all the ones I need.

I'm good to go!
