There have been a lot of suggestions here and the thread contains all the 
valid information, but some people have given you deprecated advice. So I'll 
try to clarify what can be done and how it's meant to be done.

1. Your own scripts belong int /usr/local/etc/rc.d, if you update your system 
it will suggest to delete all custom scripts from /etc/rc.d, because it's only 
for scripts from the base system. Remember that path will not be set when your 
script is called at startup. The usual approach is to only use fully qualified 
filenames.

2. All executable scripts in /usr/local/etc/rc.d are executed at startup and 
given the parameter start. Upon shutdown the parameter stop is given. The name 
of the script does not matter.

3. To this point you have all the functionality you asked for and there is no 
need for you to look further. However you are at liberty to instead build a 
compliant rc.d script, which brings you the advantages of controlling the 
execute order by defining dependencies and being able to activate/deactivate 
scripts and additional parameters in the file /etc/rc.conf.
If you wish to exploit these advanced features it's a good way to look at 
existing scripts in /usr/local/etc/rc.d and read the rc(8) manual page.
