The RedHat/Centos way of doing things is to have init scripts in 
/etc/rc.d/init.d that take at least start, stop, and restart as arguments for 
each program that should start automatically.  Then for the runlevels where you 
want them to start you have a symlink where the name starts with S and the rest 
is a number to make it sort alphabetically into the order that things should 
start in /etc/rc?.d (where the ? is the runlevel).  Likewise add links starting 
with 'K' in the levels where the process should be stopped.    There is a 
convention for comments in the scripts so that 'checkconfig program on' can make 
the links for you.  Look through some of the other scripts to see how they work.
