Ok folks. I'm looking to setup a wireless network at home but have little idea what I need.

I have a Dell Latituede D600 with built in wireless
Dell 4500
HP LasterJet 1100
1.5Mps DSL via Qwest

I'd like to add some sort of 200g hard drive that is accessable from all computers. Same with the printer - I'd like to print from any computer.

What all do I need?

Thanks,
annerj
