Other than that, I would chop a bunch of stuff (around 70% or so).
All of the mana dorks can go in favor of cards that get more land into play, as an example.
I am also not a big fan of one-shot pump spells for EDH. Think more in terms of reusable effects and evasion for Omnath.
Some cards that have been clutch for me in my Omnath deck:
Most successful Omnath strategies are dump a bunch of lands, pump Omnath, play a huge Genesis Wave hoping to hit Avenger, Crossroads and Craterhoof. Swing with everything. Or slowly build up a ton of creatures then Tooth and Nail for Avenger/Craterhoof. Swing and win.
With some luck and a well built deck it isn't uncommon to belch pretty much your entire deck onto to battlefield by turn 6-7. Sacrifice a giant Omnath to Greater Good. You still have all that mana in your pool. Cast Lotus Cobra. Cast Azusa, Lost But Seeking. Cast Exploration. Cast Oracle of Mul Daya. Drop your 4 extra lands. Cast your mana doublers. Cast Boundless Realms (getting landfall triggers off Cobra). Cast everything else in your hand. GWave for whatever is left in your deck.
Basically with enough extra land drop effects, mana doubling effects and Lotus Cobra's landfall you can turn Greater Good + Omnath into "draw your deck, play your deck". Add Crossroads plus a way to recycle Rofellos (Greater Good + Eternal Witness or Regrowth) and it gets even easier to play your whole deck at once.

Some cards that have been clutch for me in my Omnath deck:
I know that's a lot, obviously pick and choose ones that speak to you..
Also, since Emrakul is banned replace with Kozilek, Butcher of Truth.
