You could read several good books on the subject.  This is far too

For free software, check out AMANDA.  For commercially supported 
software, check out BRU.

Simply patching your system is a good start, and for that I recommend 
that you install apt-get or yum on your machine and use those tools to 
update your system regularly.  Both of these tools are fairly automatic.

Security is a process, though, and patching alone is not enough.  
Again, entire books have been written on this subject and it is too 
broad a subject to address quickly on a mailing list.

> Daily log checking,

There are some programs that claim to do this, but in the end I've 
found I prefer to just page through my logs once or twice per day, 
skimming through and looking for things that stand out.  Doing that in 
combination with one of the automated log analysis tools would be a 
good idea to consider.

What you're asking for is a book on Linux administration.  There are 
many good ones out there between $35 to $60 in price.  Or you could 
take a few weeks of training for 100x that price.  Of course going the 
other direction there are many good documents out there for free (see 
the Linux Documentation Project, as well as the great docs that came 
with those Red Hat CD's).

You'll save yourself a lot of reading time if you switch your MTA from 
Sendmail to Postfix.  Did you happen to catch the Postfix classes that 
TriLUG hosted recently?

Wow you have some deep pockets.  You'll have no problems affording 
those books.  Or a consultant to handhold you through this transition 
(*wink*)
