Slackware Linux. Perfect balance of security and stability and with a
custom-generic kernel the RAM footprint is comparatively tiny and makes
for a very responsive server.

Whatever OS you choose, make sure you do a manual RT install, don't rely
on someone's pre-packaged system. Also, I recommend making sure all of
your perl modules are installed via CPAN not a packaging system to
ensure no upstream modifications and a simple upgrade path. In Slackware
both of the above are a given.

Debatable. I would probably say Ext3 myself, but then for the level of
transactions you're talking about you are on the border where J/X/Reiser
could prove themselves useful. Wouldn't hurt to do some benchmarking.
For what it's worth, don't take recoverability into account in your
decision, just make backups. Trying to perform file-system data recovery
in that type of environment is a waste of time on any FS.

Apache. No Question.

Debatable. I think for me it would depend on what is in use in the rest
of your architecture. If you are a fully MySQL house, as we are here,
then it makes sense to keep it all the same since you can share
primary/failover servers and your people-processes are harmonious. If
you don't really have a dependency on either then... well it's up to
you. I'm used to MySQL and having it at the core of nearly all
DB-dependant applications here has been useful, but many would argue
that for a larger system like yours PG wouyld give you better
performance. Again, a bit of benchmarking wouldn't go amiss.
