Benny - thanks so much for replying. 

I was able to find the necessary parameters to adjust the "check_procs" plugin, from there I see that I can modify this in the monitored system's nrpe.cfg file. So I edited nrpe.cfg relevant line for check_procs to read as:

command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 1000 -c 1500  

then I restart munin-node:

/etc/rc.d/init.d/munin-node restart

Now I just got to figure out my other Nagios issues. Maybe another thread later. Thanks again Benny, and of course to the entire Nagios User list. Such a great resource
