General rules, not specific to this company or layout program:

Run DRC and check annular ring size with final drill sizes. Watch that
silk screen markings (which always seem unimportant) don't wind up on
SMT pads. Double check all hole sizes. You do NOT want them too small,
and too big is almost as bad. Check power pins to make sure there isn't
an isolated net that didn't get connected; it's often a good idea to go
through the netlist and just look at everything there. Make sure you
don't do anything really stupid like flipping a part or getting the
wrong footprint by printing out the PCB 1:1 and setting parts on
top of it. Especially double check footprints that you created for
wrong pin numbers relative to their schematic and physical layout.
