Mcmaster can ship your order same day provided you order early enough. They usually get my stuff out same day and arrives next day...granted I live in same state, but they're shipping is crazy fast. Pistons/rings look fine. Get new set of gaskets...base, exhaust, bpipe etc from Jetmaniac. Stuff should get there Wednesday/Thursday. U could rebuild, check compression and be on water Thursday/Friday. You could order an extra set of rings, but if you're looking at an eventual bore you may want to wait till that goes down. I've done a midseason hone and new rings when I bumped up compression on an engine of mine.
