well from the looks of what you have its a little but too much on the dmg and not enough on the support. the lightning orb, chain, flash, lightning javelin are fine but depending on what your secondary class is you can add a bit of stuff to that. My ele happens to be a mesmer secondary so I have like 2 spells from mesmers in my line up. Um...elites you would want to have for lightning would be lightning surge which is in dragon's lair
I don't really know of any other lightning ones....another good ele one is elemental attunement or ether renewal ...I don't particularly like the renewal one just cuz I don't really have that many enchantments....but that should help you out a little.
