kernel upgrade probably not very important. As others have pointed out,
there is little reason not to upgrade MS and SA. Stick as much memory in
the box as it can handle.

if you are "inundated" then the best start you can make is to reject as
much as possible at the MTA. As this is Debian, your MTA is probably
(but not necessarily) exim. Look at putting in a single well regarded
block list at the MTA, something like zen.spamhaus.org but do your
research and find one that /you/ like the look of (block list
preferences can start flame wars!). Make sure you are rejecting mail at
the MTA for all unknown recipients and not accepting then bouncing. Set
up your MTA to throttle incoming mail so it doesnt get overwhelmed or
let your incoming queue build up uncontrollably.
Visit the MS wiki for tips on how to do this - dig deep, it can be a bit
tricky to find what you are looking for. Search the archives for good
links into the wiki.
