Order the BT line ASAP - it'll probably take days to set up, and you can't apply for ADSL (which does take several days) until the line is active.
Does your house have a fixed TV aerial? If so you may need to upgrade it to receive DTT.
I'm currently with BCN for ADSL, but about to switch to A&A (and regrade up to Max at the same time) - purely on price grounds, BCN are good and clueful and A&A have a good rep for same. The BT checker can be a bit variable when given a postcode - you'll get a more reliable answer when you have a real phone number to feed to it.
