help setting up a wireless network

Nearly every router on the market these days allows connection of up to 4 computers by a wired ethernet connection.  Furthermore, it is always a good idea to have at least one computer connected by a wired connection so that you can set up the wireless connection and troubleshoot the wireless connection when you can't connect by wireless.   So long as you can connect to a broadband modem by etherent, then just about any router will serve your needs. 

On another matter, note that a Pre-N router has proprietary features that will only allow the Pre-N capabities of the router to work with wireless network adapters from the same manufacter.  Note also that the adverstised Pre-N speeds will have absolutely no effect on the speed of the internet connection, as broadband internet connections are generally less than about 5 Mbps.   So, you might want to reconsider the Pre-N router and save yourself some money by just getting an 802.11b/g router.

To second volcanoe, I would avoid any "802.11N" devices until there is at least a single draft.  There are currently two different versions out there and one of them will lose -- even if you make the right guess, say "pre-N" for example, there is no promise that the devices will work with true 802.11n devices when the standard is finalized.
