OT: Computer Networking

[Atrocities]

I was wondering if any of you know how I would go about setting up a home network? I want to rip all my dvds to one computer, put all my music onto it as well and then have wireless access to those files from any computer on my network. Is this possible? What do you think I would need in order to accomplish this?

Also for you FireFox users, is there a way to permanently set the page size so that I don't have to increase the text size manually every time I open FF? On the LapTop the font size is way way way to small and I have to size up two or three X in order to be able to see the text.

Thanks.
