Re: pin voltage while programming
Depends how you design your thing. On most sensitive programmer, you can set the target Vdd voltage, that solve the problem, if any. An home made LDO for Vdd and resistor divider for PGC/PGD? could be this too. Never tried it though.
You can Isolate your PIC from the "external world" with jumpers and diode, that's for sure, but first, check what happen on I/O while programming. I doubt you'll see 5 Volts peaks, more likely some spurious volts.
Another thing... does this board will require some firmware update? Case not, you could just solder the pic on, program it, then populate the other components.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
