Question : setting up a network with ADSL

I am completely new to networking. I will be moving to a new house that we are building at the moment. In this new house we have five bedrooms and study that all have three access points in them each. These all run to an attic. I will be installing ADSL into the house. What would be the best netowrk to setup taking into account the following:
I would like to have at least five computers running to begin with (one can run as a server as it currently is not being used as anything but is fairly new AMD 2400+ procor)
I would like to have the broadband internet split around the computers
I would like to have network printing
For furture exansion would also like to be able to use a laptop wirelessly (the house is fairly large also approx. 800m squared)

What would be the most ideal setup and if possible give an estimate at cost.
If you need anymore info please ask

Thank you

Answer : setting up a network with ADSL

I would suggest that you get a netgear AirStation 54Mbps Wireless Compact Repeater Bridge-g, 802.11g, and 5
EZ Connect g 2.4GHz 54 Mbps Wireless PCI Card, 802.11g, plus a  AirStation 54Mbps Wireless Notebook Adapter with Antenna Interface, 802.11g for laptop.  They are all available at compusa and all are about $500 together.  Don t forget that you re making a wireless network!!
