Using Plastiguage?

I have personally never used it. It is pretty simple though. You apply some to a surface, torque everything down, dissasemble, then check the plastigauge against the reference card. From my understanding it is not the best method to use on our motors. A good set of gauges and calipers will be for more accurate, and yield better results. You dont want any bottom end bearings too loose.
Install the bearing lowers in the block lay a clean crank in nip off a pice of the Plastigauge with your fingernails lay this across the Crank journal then bolt the Cap down to it's torque setting.
Do NOT move the crank at all remove the cap then using the scale on the package compare it to the squashed plastigauge on the crank.
Scrape off with your fingernail and repeat on all journals.

Should I measure on multiple sides of the bearing? And by bearing lowers you mean to only have just the bottom bearing installed, not the top one? Or do I do it with both bearings in? Or no bearings in at all just the crank/connecting rod. Im a NEWB!
Ummm lay the lowers in the block
Put the uppers in the Caps
Only have to gauge at the top of the journal.
You may need to move the crank so the Oil holes aren't in the way after you've done a few journals so be careful turning it while it's dry.

Detailed instructions for you at these two links.

Seems pretty simple, is there a formula to determine the size of the bearings I need to order, Or do I just order the numbers I read off the plastiguage paper?
Ummm that's a bit backwards 13!
Plastigauge is used as a final check after the bearings have been sized to the crank.

So should I just order stock size gauges and then check with plastigauge?

Radius, Diameter, Circumference? Im confused!
Im guessing a fine micrometer would be the best tool to do so with? And then I take the results to the stealership and have them do the rest?

Diameter
And yes a micrometer is the best.
But using Toyota bearings they have many sizes based on the Bearing bore size as well so an inside snap gauge is needed.

If the motor is a virgin there will be sizes stamped on the pan rail of the block for the bearing bores.
