1. No.
2. Oil it.
3. No.
But a new chain on a worn out
cassette will result in a chain that jumps on the worn out cog(s) under pedaling pressure.
A new chain on a
lightly worn out
chainring will result in a noise as the RD tugs the chain off the bottom of the chainring.
A new chain on a
heavily worn out
chainring will result in chainsuck as the chain sticks to the chainring and gets pulled up into the underside of the FD.
