one question at a time...
based on what your doing, I would invest in some newer forged aluminum pistons, you will be clearancing the cylinder walls anyways, may as well find out what overbore you need, buy a larger piston and some new rings, and as long as your using a forged crankshaft the bottom end will last forever, you will be out minimum monies, and the shortblock will be able to withstand a lot more hp that you will obviously be trying to send its way later.
