No.
Usually the outer right bearing, then the outer left.
Or it is obvious like a torn rod or a blue and sloppy big end bearing.

And the centre webs, are they splined where they are pressed together? Never seen any pics of these parts..

Oh c'mon ... are you really that lazy?
Google rd350 crank web and you get stuff like this:

The center section is difficult to press as it's not keyed or splined but the 180 deg offset will be crucial for later trueing.

I'm doing my motorcycle mechanics school currently.
Regarding your flywheel...use contact cleaner or brakekleen on the tapers, internal and external, and then mount them up clean. Do not touch the clean surfaces, as the oils in your hand will cause problems.
For your cases, a leak down is required and afterwards a vacuum test at 6" of mercury for 6 minutes will tell you if your main seals are toasted.
