Get someone in to install phone points in all the places you want phones. This should be easy enough, they'll go round and put telephone wall plates in where you need them.
Check your phone line to see if it can get ADSL broadband. If you can, you can get ADSL packages that include a wireless router, which will allow the broadband connection to reach your laptop all around your house. The printers will need to be plugged into something like another computer or the router and be set up as shared across the network unless they have wireless features built in.
For the TV, get Sky+ in the lounge. This is a PVR and will allow you watch one channel while recording another and pause and rewind live TV. You can also order Sky multiroom and they'll fit another Sky Digibox in your bedroom which will receive all the channels you get in the lounge. It will be an extra £10 a month on your Sky subscription but it's worth it. You can also add another Digibox in another room later on if you want. Out of a possible 4 satellite cables from the dish, each regular Digibox uses 1 cable and Sky+ uses 2.
