If you really want to make your own:

1 and 3, 2 and 6. Why are 4 and 5 skipped? analog phones use center pairs,
and this allows for those to be used (backwards compatability thing with
rj45)

I second the suggestion for a hub. Useful for company who may bring 
their laptops over, and if IP MASQ uis setup, you can all geek out on the
internet. If you decide to go with a 10/100 hub, then why not pay the
extra ~$100 and get a Wireless Accesspoint with 10/100 ports too, and you
can roam in house with WEP and stuff. :-)

When you consider hubs, getting one with an uplink port is a good idea for
later expansion. (The uplink port logically does the same as a patch cable
and switches the Tx and Rx lines to allow you to connect  hub to a hub.)
