Whether it's worth it depends on how much you'll use it. The config
should always be 
seperate, and I'd suggest libexec too (We're always adding custom
plugins). If you
run in a mixed mode environment (some 32 bit, some 64), separate your 
architecture-independent perl scripts from your binaries by using two
libexec directories.

We have 35 custom .debs in a local repository. One of our nagios checks
runs apt-get 
update every night for security checking, so we see which machines need
upgrades. 

We haven't written a plugin that needs a perl module which isn't in the
OS repository. 
It's easier to keep uptodate that way, and there's arround 1400 perl
modules in the apt
Repositories. 

The testing that needs to go into the installation scripts (to do it
right) for something like 
a nagios install is much more intensive than most, which files to remove
in preperation 
for upgrade, which to purge, which not to purge, what to do on failed
upgrades, etc. Much easier 
to run one command after another and check for errors yourself.
