Excellent move. Also consider the 16F88 if this is hobby use. With twice
the memory of the 16F628, and the built in nanowatt oscillator features,
it's great bang for the buck. Also it's self programmable, so it's one of
the smallest cheapest packages that you can put a bootloader on.

Not really. Be sure that the PGM/RB3 pin is grounded via a 10k resistor
during programming. This is ensure that no ill effects occur with low
voltage programming.

Yes, but the chip erasure algorithm is a bit different than the 16F84. So
you'll need new programming software. Something like IC-prog should do fine.

No problem.

Nope. In fact building a ISCP cable is probably a good idea.
