You've got a pretty respectable list going there for your Eldar!
I've tried to write you a little sample list using as many of the models you have as possible and still remaining pretty good. It won't be powerplayer spam but it'll be fun and balanced.
It's a single detachment with 5 troop choices, and lots of fast moving stuff. Your Serpents will be your anti-air, it could just use a little bit more anti-tank as the only thing really effective for that is the Wraithguard with Spiritseer (use a Farseer model), which is why I've also put the Lances in the guardian squad. If you wanted to optimise it a bit more I'd drop the hawks and have 2 6-man Spider squads.
The big Guardian squad takes a Warlock and the Farseer goes with the Avengers (paint up your 4 extra Guardians like Dire Avengers

) The rest of the Warlocks either hide behind the Guardian squad or jump in it's transport when the game starts.
