Transfering iceweasel bookmark files to new system

[Gary Roach <gary719_list1@verizon.net>]

Hi;

I am replacing my oldest 1GHZ box with a new 2.65 x 4 GHz box. Both are 
running Debian Squeeze. How do I transfer the iceweasel setup from the 
one computer to the other and combine the bookmarks from the two units. 
As an aside, is there any way to determine the purpose of all of the 
files (and their location) that Debian installs with a package.
