When I was an admin at acm.jhu.edu, I had us use the free certificates for
.edu hosts given out by ipsca.com. They were compatible and
well-supported, and signed by the right authorities to have no error
messages. (Except in some totally weird interaction with Mozilla, for
which we opened a bug and which I *think* is fixed.) You can toy with
https://secure.acm.jhu.edu/ and connecting via SSL'd IMAP to
secure.acm.jhu.edu (port 993).
For my personal servers, I use the "RapidSSL" certificates sold by
Geotrust. I can't seem to find the link for the vendor I use, but they
seem to be widely resold for around $10-15 a year. The only serious
complaint I can find on the web is that if you use their bulk purchasing
option, be sure to read the fine print - your ability to use the
bulk-purchased certificates goes away one year after you purchased them.
As for how to set them up, I always follow the Apache mod_ssl instructions
and then use the certificates everywhere else on my system.
As for if any of this is truly "necessary," no idea. (-: I did it because
I wanted SSL/TLS.

Godaddy also has cheap SSL certificates. They give you a certificate and
another file that contains the chained certificates. You probably need to
serve both to avoid browsers giving an unhelpful "something is wrong but
I'm not telling you what" error if the cert chain hierarchy is missing.
