Which rules for specific open ports?

[<briankd () sonic net>]

I'm setting up an Apache/PHP web server behind my DSL router, and setting
the router to only forward ports 80 and 22 to the server.  I'm concerned
about potential intrusions, but I feel like I've covered a lot of the
potential exposures by using the port-forwarding scenario.

I followed the recipe at
http://www.internetsecurityguru.com/documents/snort_acid_rh9.pdf to set
Snort/PHP/Acid up on this web server.  Is there a way I can determine
which rules & preprocessors are the only ones necessary to protect against
intrusion on those two ports?
