At the moment we have one computer and one broadband connection, my Sister is getting a new computer (which has a LAN card) and wants to share the connection but obviously I don’t want to keep my computer switched on 24/7. I have been told that all I need is a router is this just a network hub? Because I already have one of these and loads of cat5 cable. Can someone explain what I need to do here it’s a bit over my head.

No, it's not just a hub, but most SOHO routers have hubs built-in to them.
The trouble with broadband, is that you can only have one MAC address connected to the cable modem. So, you could in theory have the modem plugged into the hub as well as 2, 3, 4 (or whatever) number of PC's too. Although, only the first PC with it's MAC address registered with the ISP would work.
The router acts as this MAC address and hides the rest of the PC's behind it.

NTL allow 2 MAC addresses now apparently, but you only need the one.
RP114 router from Netgear (as Super_si says above) connect the WAN side to your cable modem, the PCs to the LAN side IP addresses for the PCs will be allocated by the router.
To get the c.m to recognise the Router MAC instead of the PC, switch the CM off and disconnect all cables. Leave off overnight, then reconnect in the new configuration and away you go. It is possible to get the router to spoof the MAC of the originally connected PC instead of going the above route.
Has the added bonus of acting as a hardware firewall (providing you don't decide to open all the ports and forward them to the PCs)
