Answer 1

You have an HDD Which is giving multiple errors, through various channels, and you're asking us if you should replace it?

Yes, of course you should. As soon as possible.

If you're asking whether or not to replace the other drives, that's trickier. If they've thrown no errors yet, you will probably end up having to pay to replace them (any support contract you've got is unlikely to cover pre-emptive replacement of non-failed components).

If the drives are accessible to the OS (ie, not hidden behind hardware RAID) you might want to consider running smartctl -t long against each drive in turn. If they pass that test, you really have no valid reasons to be suspicious of them.

Consider running that smartctl test from crontab one a quarter or so, and make sure to check the output.

Answer 2

You should replace the disk that is causing errors ASAP.

You don't need to replace the other disks, unless there's an advisory for the model and firmware in cause on the manufacturer's site.

You should also search for updated firmware for the drive that's causing problems, although I personally haven't seen a critical update in the very brief google search i just did.
