Well our package was tog and assistant (who also had a camera and so took shots as well) from just before the ceremony right through until about the 3rd dance at the reception, although he made clear that if no one was dancing for the first three songs they wouldn't just leave, they were staying until he got the shots he wanted 
The prints package includes a professional album (can't remember how many prints) and a CD with all of the shots on for us to print and copy as and when we wanted (I don't think that's the same as copyright free, he still retains the right to use the shots for his website, magazines and stuff). He also did some photoshop work with a lot of the shots to add vignettes, colour pops, touch ins etc and said that if we liked an effect and wanted it applied to another shot (or wanted it removed so we had the original shot) we could let him know and he'd do that for us. For this we paid £1,250, which seems quite expensive compared to what others are getting but we liked his work and more importantly trusted him to do a good job (agree with the HIBS on this thread, a bargain price isn't a bargain if you don't get the shots you want).
Another thing that really swung the choice for us is that our tog was one of the only ones prepared to put an indication of prices on his website - not a quote, just "Package A includes x and y and starts from £850, Package B includes x, y and z starts from £1,250" so we had a ball park figure to work with. I was not prepared to phone/meet lots of photographers, take ages to explain exactly what we wanted only to find out that they were way out of our price range (or worse, feel pushed into saying ok because we had taken up so much of their time). We may have paid a little more than we could have for the package we got but we trusted our tog to be up front and do right by us and you can't really put a price on that IMO.
