dpkg -L on an installed package name (and dpkg -l to get all packages in a one-per-line format) will tell you what files a package DID install.
The CGI stuff is really an Apache question. But you might check the mailing list archives or re-read the documentation. Seems to me that the Apache config changes were documented pretty well.

Subject: [Xymon] Xymon Server in Debian
Hi Folks,
I am currently testing out Xymon and using Debian as both the server and client in my tests. I installed both xymon clients and the xymon server from the Debian repo rather than using the .deb from the xymon site or compiling from source. I have a couple of issues that may be Debian sepcific, I originally asked this question on the Debian forums (http://forums.debian.net/viewtopic.php?f=5&t=103076) but got no response.
1. I created a user using "htpasswd" so that I could access the cgi sections of the web server, however I am never prompted for a username/password so still cannot access these sections.
2. I was looking for hosts.cfg to setup monitoring of diskspace and the like but the file does not exist under /etc/hobbit where I expected it. In-fact any file mentioned on this page does not seem to exist: http://xymon.com/xymon/help/xymon-config.html
This second point in particular makes me think Debian is doing something odd with packaging and file names etc. Any help is greatly appreciated.
