I'm sorry to bump this, especially after you've declared this finished, but I thought I should point out a few issues. First, the minor. When T'Bok wing arrives through the jumpgate, you should make sure that you remove the wing's self-generated warp effects, and make a giant SEXPed warp effect at the jumpgate, since that's how things work in the B5 universe.
Secondly, at the end of the mission, when the Ra'Mak gets destroyed, the G'Tok should be a little further away before destroying it. When the ship gets destroyed, often pieces of debris end up hitting the G'Tok and causing heavy dammage.
Next, in the briefing stage 1, you have one line that is an incomplete sentance, beginning with "but". This should probably be something like "the ship suffered heavy dammage and we have had no further communication since the attack".
I'm also curious about your choice of secondary weapons. You appear to have given the player wing some heavy anti-capital bombs rather than anti-fighter weapons. I would have issued the later, so that the beams of the G'Tok can take down the cruiser.
Finally, I am somewhat concerned over the ingame messages. Its not that they are too closely clustered, its that certain key messages get delayed by others. For example, you finish scanning the Ra'Mak, but you don't get the message commenting on their results until more messages have gone by. Same thing for the arrival of some hostile wings (not the automatic messages, as these are deactivated). You see the hostiles on your radar, but the message warning you about them may not come for 10 seconds or so.
