As to refitting the crank, you need to establish the turning torque firstly after fitting, to ensure it is not tight.
Refit as normal, I use std engine oil to lube the shells, after thoroughly cleaning everthing in sight, then refit with shells and thrusts, check thrust is correct I run around 4 thou on a used set of the older sort.
You should be able to turn the crank by hand no problem(no rods etc attached), that's assuming the clearance etc has been done for new bearings correctly, I would in your case check with some plastigauge just to be 100% safe.
My mates just had a crank screwed by a certain engine centre in norwich, they ground it 1 size undersize then supplied him bearings for 2 sizes under, but still not accepting it's thier fault.
