Interesting battle. In retrospect for the EA I would suggest:
1. Drop the Warlock for 2 Command Omegas or a Command Omega and 2 regular ones. As you found out, though it is a lovely mini, the Warlock as an armageddon ship, sucks.
2. Drop all the Starfuries for T-Bolts. Vorlon fighters, if he even takes any, suck in dogfights and even T-Bolts will eat them. And as antiship fighters, T-Bolts are obviously a much better option. (also they will die less to EM pulses)
3. Drop the pulse omegas for standard ones. This one is just my personal opinion but against vorlons who are all hull 5, beams can do ALOT of damage and the extra range can let you start hurting them sooner (and crucially can let you do enough to kill one or two ships at the start of the game before you start taking losses)
4. I'd consider dropping the Novas and Hyperions for more Olypus and Artemis or maybe another Omega. Hull 5 relatively expensive ships are just asking to die against vorlons and theyre all relatively short ranged ships too so if theyre in firning range so are the vorlons. Also with the big boresights for all the omegas you need lots of initiative sinks
5. Seriously consider targeting the transports first. They die much quicker than his tougher ships and lose HIM initiative sinks.... Your biggest advantage is outnumbering him, the more you can do so by the better.
Destroyers are the next priority (though if you CAN be pretty sure of killing a destroyer do that over a transport).
LEAVE THE CRUISERS TILL LAST!!! The light cruiser doesnt actually do THAT much more than the destroyers anyway and are so damn tough that they can pretty effectively 'tank' most of your fleet for several turns.
