Always use a some 3/8 fuel hose shoved over the rod bolts ...Poor mechanics crank journal protectors....

Yess
The rockers are guided by the plastic buttons in the shaft....The side play is perfectly normal.
Replacing the buttons is a good idea on a high mile engine.....

Yup
Gotta smooth out those dings.....
As long as they are below the surface you will be fine.....NO BUMPS ALLOWED.....Get the ding smoothed off and polish the journal with 600 grit emery strip.....
Around the journal.

Get some 3/8" fuel hose and cut off some pieces that can go over the bolts.
THESE KEEP THE DINGS from happening.

The copper in the bearings is showing the wear.....

Did you mark the rod and caps to keep them in pairs ????
