Bearings and Oil Pump

[Rengrave@aol.com]

Hello everyone,

I am about to perform my first Main bearing and Rod bearing replacement due to
low oil pressure and noise when I rev engine.
I am told that I should use Plasi-Gage to determine the amount of wear on each
bearing, is this easy?
I am also going to replace my original oil pump while I am at it, the pump is
worn with deep lines on top of every lobe on the center gear. 
My question is :  Where is the best place to purchase new Bearings, Thrust
Washers  and a new Oil Pump? TRF?
