Great. Last question, I promise! If I am only using that pin for MCLR, do I even need a resistor? Can I just program with a trace running from the ICSP to RA3 or will that damage the PIC for some reason?

You need a resistor from MCLR to Vcc to hold it high in normal use - this has nothing to do with the programming function.

You need not use any resistor or diode on the MCLR line from the ICSP connector On the other hand, your should make sure that the ICSP connector does not power up your entire circuit as it may end up loading the programmer supply!!
