Suggest good "how to" for networking

Can anyone suggest a good clear source or "how to" that will give me what I need to know to set up a home network including a wired network of several computers (apple and windows both) and printers between two rooms and also incorporating wireless in the whole house?

Here is one Web Site that has a lot of useful information including a lot on the basics.
