Stripe width of the filesystem is just a parameter used to optimise the pattern of writes. You can change it on an existing partition and it will be used when writing new data. However a RAID5 with 3TB drives isn't very safe, you should think about using RAID6 at least.

A couple of times I have found HDDs to start working for a short period of time after plugging them in and unplugging them multiple times. I would do the logic board swap as a last ...

Still, don't trust the RAID card 100% - make a note of exactly which drives are participating in the 2nd VD in case a "retag" does become necessary. Recreating the config on the problem drives is possible too if the import ...

You can't. See where it says FAILED? That means your data is gone. RAID 5 can only sustain one failed drive, and generally speaking, is evil and to be avoided as if it were radioactive. Remember kids, only people who hate their data use RAID 5.
