The canonical answer is "Buy Intel."  But they're surprisingly hard to
find.  And apparently, Crucial's new drive has overtaken Intel's fast
drive in benchmarks anyway.

As you can see, there's a big difference between drives.  Which makes
picking them up kind of tough.

When I bought my SSD for my laptop, I tried to find an Intel drive
online but couldn't.  So after being jerked around by NCIX for a bit,
I just went into Canada Computers and asked them for a fast SSD around
64GB (it was about a year ago).  I just trusted them, but a safer
approach is probably to get their recommendation and then research
benchmarks on that drive.

RAID 1 or 5, sure.  Although the drives are already pretty expensive.
You're probably better off with just making sure you're backing things
up, like any other drive.

I'd never do RAID 0.  Sure it's probably really fast, but you're
doubling the risk of drive failure.  And when an SSD goes, it goes.
(Mine hasn't gone yet.  Knock wood.  I keep data on spinning disks
anyway, because they're big, cheap and it doesn't need to be fast for
that).
