You don't need Eldrad. He's overrated by too many Eldar players in my opinion, and is only of really significant help when you absolutely need double Fortune to make your list work.
I'm with Atnas about diversifying the Warlock squad. You need to give them a shooting role for the turn in which they disembark from their transport, otherwise they are sitting ducks. As a result, I would definitely suggest that you find the points for around three Destructor powers. You could drop the Runes of Witnessing to find some points, and you could also consider removing Guide and Spirit Stones if absolutely necessary, since it's only really the Storm Guardian squad which truly benefits from Guide in this army.
Regarding the placement of the EMLs, I recommend that you switch these to the Wave Serpents transporting the Defender Guardians, since these don't have to get as close to the opposition to allow their units to disembark within range to open fire with at least one weapon. As a result, they are more likely to be the second wave, rather than the first wave, so a longer ranged weapon is more useful.
By the way, I know that Eldar Runes ruin the opposition's plan, but there's no need to let him/her know that in advance through the spelling
