Hey, welcome to Dakka
This list needs a bit of work though i think.
From your comments i'm fairly sure you haven't played with this yet (or
40k at all?) So its quite hard to get a decent list there immediatly.
First things first, your list isn't focused. You have some footsloggin units and 2 tanks (transports)
You either want to go all mechdar, or footdar.
So your options, for footdar, drop the farseers, the banshess, the wave serpents, maybe the warlocks. Add in Avatar and Eldrad. Storm Guardians don't really work in footdar though. War Walkers and Wraithlords are good. Guardians with Bright Lance or Scatter Laser (near avatar, so they are fearless). You can then add things like Scoprians, Harelquins for some extra assault power.
For mechdar (which doesn't really fit Ulthwe as much i don't think) you need all units in wave serpents, you can use war walkers, but Fire Prisms or Falcons with 5
DA work. Storm Guardians with 2 flamers and destructer warlock are nice, or Dire Avengers.
I'm not an experianced Eldar player (only played Duel Seer Council on bikes, which is quite good, but its almost auto win/lose in most games, so isn't always that fun) So someone else will probably give you some better advice soon, but i think that covers the basics and should give you a better idea on how to build your army.
New codex, well it might be out next year, but seemingly Necrons, Tau,
SoB, Templars all definatly being done before, I think you will be fine starting your Eldar army now.
