Is there a STD grade for them (Main and Rod)? Or do you have to match up the numbers and have the exact grade?

In short...
OEM -> No STD
Aftermarket -> Yes

Like most manufactures nowadays the tolerances are getting tighter. Nissan, Honda, and Subaru have the same type of color/numbering system. You'll find everything you need in the FSM, start there. If you have any questions then post up.
