Looks quite good! I am fairly sure there were quite a few expanded universe details in the DS9 book or one of the suplements. Been a while since I dug those out. And remember, it's not a Wormhole, it's a 12 Dimensional helical, Verteron driven tunnelling phenomenon
If you can pick it up the DS9 technical manual is a great book (even if most of the sizes and speeds of ships are horrendously inaccurate!) It's also got deck plans of the (smaller version) Defiant and a lot of the Stations deck layout
