Err, why not take advantage of the Quadplay package (

Basically, starting September, you can get the existing 3 for £30 deal and a virgin mobile contract for £40, or you can take any combination of Phone, TV, Broadband and Mobile for £10 for each option. So, if you wanted just TV and Broadband, it would be £20.
Failing that, if you aren't bothered about Broadband, just take the Phone and Free digital TV option.
In answer to your second question, yes, they will send an installer round.
