It's usually recommended to have servers on Stable. The "unstable" in
Sid doesn't refer to the system that runs Sid, or even the individual
packages so much, but rather to the every-changing nature of the
available packages. Today you might have Foo version 1.2 and tomorrow it
might be version 1.25 and the next day it might be version 1.7. If you
setup a box with Sid and get everything working the way you like, you
can run fine for years without any problems, except if one of the
packages has a bug/vulnerability. Then of course you'd want to upgrade
that package, but if you upgrade Sid, you might wind up upgrading half
your system, and what will that do to your perfectly tuned box? Stable
has a special repository of security patches which is designed to keep
Stable stable with the ability to patch; Testing and Sid do not.
So if you need 24x7 uptime on your server, Stable. If it's just
something you're tinkering with and want newer packages and can live
with an occasional week-long brokenness is some package or other pretty
often, then Sid.
With Stable, you can also use Backports to get newer versions of
software, but I've never tried that and can't recommend it one way or
the other.

Installing from Knoppix is easier generally (provided you're on x86
hardware; installing on Sparc or PowerPC, etc, of course eliminates this
option). However, there are two disadvantages to this:
1) Last I tried, Knoppix wanted to install everything into one 2GB or
larger partition. I like to have separate partitions for /, /usr/,
/usr/local/, /var/, /home/, and /tmp. To accomplish this on a Knoppix
install means lots of partitioning "magic" after the install. Nasty.
2) You wind up with a machine that is a mix of Stable, Testing, and
Unstable, along with other 3rd-party repositories. Upgrading might get
pretty nasty in that situation.

No. See Disadvantage #2 above.

I believe a smooth upgrade is only guaranteed from one version of Stable
to the next. However, lots of folks here upgrade Unstable everyday. Of
course, lots of folks run into broken-ness everyday also. If you can't
handle glitches, stick with Stable. (Most of the glitches clear up on
their own (well, by the Developer's efforts, actually), but sometimes
you have to actually fix the problem, although this list and/or Google
and/or other resources will generally provide the Howto on the fix by
the time you decide you'll have to fix it yourself. But not always.)

Never done RAID; can't speak on it.

If you need 24x7 reliability; Stable. (Usually for servers.)
If you can stand periods of broken-ness, and want newer software, Sid.
(Usually for workstations -- still more reliable than Windows workstations.)
