I recently got some SSDs, and decided to use one of them (a 256G

from a user perspective, nothing seems different, just faster.
I would:

That is the bit I'm not sure how to do so the change is mostly
undetectable.
I once heard a speaker who worked as a Linux system administrator on
Wall Street state:
"You should be able to pick any computer at random, throw it out a 7th
story window, and have a replacement in operation within 2 hours".
The key is disaster preparedness and disaster recovery. Expect that
your computer(s) will break, and prepare for it with backups. Verify
your backups by doing recoveries and comparing the source against the
recovery. [1] is dated, but will get you thinking in the right
direction. A related technique is disk imaging. Another is archiving.
Learn them all.
Learn how to write shell scripts (or Perl, Python, etc.), so that you
can automate repetitive tasks and get consistent results.
Do not be afraid to spend money on a spare computer, spare parts, and
bigger HDD's.
Keep records of anything and everything that matters. Use a version
control system.
