In theory Wireless G should cover 450' Indoors... however, practice rarely matches with theory. That said, I'm still using Wireless G at my place and it covers around 380' in all directions, so... yeah. Depends on materiel in your walls of course. Another thing to consider is that Wireless N isn't that much more than Wireless G these days, so you may as well get an N router (it is backwards compatible with G, and often with A and B also...) that will suit your needs.

Things to consider:
1. Your current computer can continue to be connected how it is now. When you get your WiFi router you will unplug the ethernet cable from your computer and plug it into the "Internet" port on the router. Then the new cable that came with the router will plug into one of the ethernet ports on the router and then into your computer:
Modem------Router------PC
2. Laptops all have wireles cards built in these days. Otherwise Twitch linked to a great USB card if you need it.
3. Most routers have 4 ethernet ports, so if your childrens' PC will be in the same room, you can probably just buy an Ethernet cable... depending on locations of course.
4. Try and get a router that is compatible with DD-WRT, as that is a firmware replacement that gives you far more control over your device than any stock firmware out there. This is a list of supported devices. I recommend getting a Belkin, Netgear or Cisco (not Cisco Linksys aka Linksys... man have they gone down the toilet) or even the TP-Link brand that Anthony is using.
5. If you can't or wont use DD-WRT for some reason (like fear of flashing custom firmware) then get Belkin or Netgear.
6. If you need help/have questions... ASK!
