First of all, DDK, thanks and welcome to AC.
I'm probably jaded, but best advise I can give is take you time. Assemble dry to develop a game plan so when you start gluing up there's a clear path to the goal line. Run screws in and out of the crossover mount holes before assembly to ease installation later. And something I realized just recently is NoRez is easier to install if temp is a little higher. Temps in my shop are low 60's this time of year and after I installed NoRez I aimed a hair dryer in the box for a for a minute or two and applied pressure again. The adhesive is pressure sensitive and wants to be intimate with the MDF
Last bit of advise is ask questions if you're in doubt. Much good advice to be had here.
