Yep, cups are worn...
But this hub is for 20mm axle.
I looked on net and all shimano 20mm hubs got different axles (inner, which carries cups).
It looks like left side cup is one piece with axle...
Meanwile i found new spare part from shimano but price for that is spicy ????

Ahh. bugger.

Shimano spares usually very reasonably priced. Where you found it?

You're saying wrap it twice around the rim. All the way up the edge where the bead sits? Will that make it so the bead doesn't sit snug?
Thats what I'm saying, It makes a tighter fit, makes it more resistant to burping and makes initial set up a little easier. Use soapy water when seating to bead.

The tape should cover the full width of the inside of the rim. Like this:

So I'm cutting the tape so that it doesn't go up the inside of the side wall on the rim where the tire bead sits?
You both are saying 2 different things. But I've heard to not put it up the sidewall.

I'm pretty sure ajax is saying the same as me. I thought there was some confusion, so I figured a pic is worth a thousand words.

Either way, what I say is the correct way to do it...(yes I am an arrogant bastard)

It's bb92. Technically bb92 is for 68/73mm cranks but the only difference is the plastic spacer, which you don't need as the bb shell is completely sealed.
Confusingly bb71 is shimanos product code for their bb92 bb, which is what you need.
