For routers I've had good luck with Linksys and D-Link.
If your not going to be gaming the Mac is pretty slick, I've got 2 windows machines running downstairs that I've hardly touched since getting a Macbook. With no virus or spyware worries I'm a convert. When your operating system doesn't have to run on every possible PC configuration out there things run pretty smooth.
My kid has another two Macs running as well, and we have three additional hardrives and a printer that all play together on the same network.

I also just converted a friend to a Mac and transfered all her stuff over no problem.
With "Black Friday" this week in the States there might be some discounts at Apple.
