One thing that I forgot to mention about your setup is that you
set everything up before securing the box...and that is bad. 
Best practice dictates that you secure and patch the box before
even hooking it up to the network, although that is sometimes
really impractical so you do what you can.  Especially with
Solaris 8, I did a netstat -an on that OS after a default
install and basically fell out of my chair.  And it doesn't
sound like you did a minimal install either (but I'm just
playing a hunch here).

I've got the basic snort and reporting systems up and running

ACID, MySQL) and I'm ready to turn my attention to
protecting/hardening
my system (Solaris 8 on SPARC) before I do any more with snort
(barnyard, oinkmaster, etc.)

I'm looking at a tool (yassp) for going beyond the system
hardening
described in the docs.  I can't find any mention of it (so
far) in the
archives, FAQ or the recommended three books.  Yassp seems a
bit old. 
It may work well for Solaris 8, but it appears there's been no
recent
support for it.

Does anyone think it's worth hardening a system so much?  I've
already
got tripwire running but that, to me, is a reactive approach. 
I'd
rather prevent someone from changing my system files than to
know they
already did it.

I'm aware that unless I proceed carefully I can make the
system useless
for its intended purpose, running snort.
