They will never answer that damn phone - don't bother trying.  
www.britain-usa.com should have all the stuff you need.  Do an e-fasttrack, get your two visa photos, gather your documents in the order they are requested on the form, that's how they will ask for them.  Get a cashier's check from your bank, dress neatly and show up on time.  There will be a man with a clip board outside the consulate with all the 'visitors' printed on it.  He'll check off your name, give you a paper badge.  You will pass through security, up the elevator, queue in a line and they'll call you.  Hand over your docs, they will make copies, give you a number (like a deli) and tell you to pick up your visa in an hour.  There's a Starbucks across the street.  Pop back in an hour - give them your number - and your in!  Then go celebrate with your honey!!
