Laurie,
Yes I have a DSL connection, and I do make it sound a little more easy then it really is .. I am by far not an expert by any means,
the things I used as reference are as follows
For the server OS FreeBSD -
http://www.freebsd.org
for the web server Apache -
http://www.apache.org
for the DNS A Record (to point the domain to the IP of your server) -
http://www.zoneedit.com
I dont know that I can really offer alot more then that, I have had experience working on servers in the past and so I just built on that and did a little reading and a lot of hair pulling
let me know if you have any more specific questions ...
