Main/Rod Bearings/Thrust Washer Replacement

["Steve Nabors" <topdown@eudoramail.com>]

Listers,
I'm about to replace my main bearings, thrust washers and rod bearings(TR6). 
I've dropped the pan and have found no spare parts(thrust washers in the pan). 
Looking up at the crankshaft, I noticed the counterweight between the number 1 
piston rod and the front main bearing had the following stamped on it:

010
010

Does this mean my crank has possibly been turned to accept 010 undersize 
bearings?

Regardless, how do I measure the crank journals, I've heard of plastigauge but 
never used it or do I need a micrometer or something else?
