You can make the cabinet a little shorter and deeper if you want. Just keep the internal volume the same and it will be fine. Port placement is generally uncritical; Just be sure it is unobstracted and don't put the port entrance right near the midwoofer cone where midrange frequencies can enter easily. It's nice if the port faces a panel with insulation so that midrange frequency energies are attenuated.
