[Q] Peer-to-peer with Windows XP + Internet Connection Sharing


Dear all,

I have a home computer with Windows 2000 SP4 installed and an ADSL USB modem to dial-up to the Internet. My laptop from work has Windows XP Professional SP2 installed. If I bring home my office laptop, I would like to share files between these two computers and share the ADSL internet connection of my home computer.
I have no hub, but a crossover UTP cable between the Ethernet cards of both computers.
I have several questions:
1) do you need a hub for this set-up, or can I manage with the crossover cable ?
2) before, I used the NetBEUI protocol to share files between two Windows 2000 computers, but this protocol is not supported anymore. If I connect now my Windows 2000 home computer to my Windows XP office laptop through the crossover UTP cable, my Windows XP laptop does not find my home computer. I have switched off the Windows XP firewall.
At work, my office laptop is configured for DHCP.
How can I take the first step to share files ?
3) how do I setup the internet connection sharing ? The Internet connection sharing between my home computer and my office laptop should go through the LAN connection with the crossover UTP cable, but if my ADSL modem is active, my "Network and dial-up connections" window in Windows 2000 shows also a LAN connection "ATM connection" for my ADSL line. Then there is the other "Local Area Connection". Which ones do I need to share ?
Which TCP/IP settings do I need for my Windows XP office laptop ?

I already searched through the newsgroups and the website practicallynetworked.com, but I am afraid I need a more easy-to-understand description of the different steps I should take.
Can anybody give some suggestions or point me to a relevant website ?
