Bostra would be the only one it could trade with anyway, since they'll opt for the far less lucrative overland trade to Thebes and Petra.

So, no, don't build it at all.
This is correct. I built a port in Memphis (specifically so I could built a few biremes to take out these annoying pirate ships that were blockading Thebes' port), and found that - even after the blockaders were killed off, it wouldn't do any sea trade with Thebes, or with Petra (which I now control) or the other port city on the Arabian peninsula. Very annoying, and I can only imagine that it has to do with how narrow the Reed Sea is (not the Red Sea, the Reed Sea - the narrow part west of the Sinai).
