You can simply ignore the lines to the Wisp628 if you don't use that
programmer. (But you will have to connect your woen programmer in the
appropriate way if you want to do ICSP.)

The unused pins of the target PIC can be left unconnected for now (in a
serious project you might want to add pull-up or down resistors, or make
the unused pins outputs).
