Uneven frets, too high action, buzzing

Hi all.

I'm learning how to perform neck set up. I set relief to .010", but it buzzes at the 12th fret. I found that some of the frets are uneven there.

My question is should I check for uneven frets AFTER setting relief, or use a a notched straight edge first. I know I'll have to adjust the truss rod for the latter scenario.

My goal is to get down to around .007" relief. Does the tailpiece affects the action?
Sorry for all the questions, but I'm new at this and don't want to ruin my guitar.

Its a Les Paul Standard. Ernie Ball 10 gauge strings, Super slinky.

Thanks in advance

Set the truss rod first...always.
Uneven frets can be spotted with a straightedge long enough to span 3 frets.
A 12" mechanical ruler can be cut into 3 pieces (with some left over) to accimplish this.
If you're new at this and worried about ruining your guitar, all a rocker will get you is information.
Not that information is a bad thing, but if you find a high fret, there won't be much you can do about it.
