The significantly higher bill from the bike shop was a communication problem on their part, but your bike probably needed it. It would not be inappropriate to say you at disappointed with their...

You could try asking a shop with a Sram direct account,but you're probably SOL. Even if they intend to offer it as a replacement part, they're crazy back ordered on almost all small parts.

The crankset is the better idea by a large margin anyways. Obviously a compact 6700 crank will match the aesthetics of the rest of the group set the best if that's something you care about. Tiagra...

Ball bearings are so cheap that it's pretty much always worth replacing them if you're servicing a cup and cone hub. The hubs, if Shimano, should have their model number printed on them. You can...

It'll work OK. Shimano specs give 40t as the minimum large cog size on RD-M8000, so shifting may be slower than ideal, but the cog spacing is the same.

Not compatible. You need a road triple fd, ideally designed for a 52t big ring (some are designed for 50t, you can probably get one to work but it'll be worse. )
