I have 20 to 3o computers on my network and I have a copy of the debian packages on /var/cache/apt/archives but when I take this downloaded copy to any other machine I need to hit an "apt-get update" , How do I avoid this ? Where is the list of packages which is updated by that command stored. I need to copy them as well, and use it on a computer which is completely offline.

The packages lists are stored in /var/lib/apt/lists/, copy all the files inside that directory (except lock and partial) to the other computer. You could also copy the .bin files in /var/cache/apt/.

Well, the apt-get update command updates the pkgcache.bin and srcpkgcache.bin files in the /var/cache/apt/ directory, so you have to copy those files too. Also please note that what you are trying to do it is not recommended!
