Don't use grease in an oil pump to help prime it- use Vaseline. Grease can clog an oil filter and Vaseline will not.
No need to line bore when installing a new crankshaft- check clearances, install bearings, apply oil to bearings, install crankshaft, torque caps. If the crank will rotate using your fingers, all is well. If the crankshaft was somehow a problem, say the #2 main journal was out of position, how will line boring fix this? It won't. If it was good with the prior crankshaft it will be good with the new one or something is wrong with the crankshaft- not the block.
The pistons need to freely "flop around" on the wrist pins.
It sounds like the oil pump never fully primed and this is what killed your engine.
