I had all the X-Members in prior to installing the lines. I'm not sure if it matters, but one thing I might be worried about if I installed the lines first is if I accidentally bashed or smashed a line trying to get the X-members in... The Fuel and Brake line run a long the top/bottom of the Transmission X-member if that makes sense.
Check out my pictures before I tore it all down. This is a link to my drop box account with about 41 photos. I made annotation marks what line was what to help make it easier for any to use as reference.
