The official National Dex guide for ORAS.
Yes get one of the 'Pokémon Handbooks' (probably this)
Or this when it comes out, although it's more of a strategy guide.
Or you could just play around on the Pokédex section of the Pokémon website.

Already launched in the US
Well there's this.
Also it's a strategy guide, unless you skip ahead to later sections you'll be fine. And you can just reference it after going through a route to see if you miss anything.
As for your other question, I'd still probably start with XY, it's got a few more things for beginners and you won't be inducted by as many new systems.
All the pokemon in the Kalos dex are available in Kalos, it would be weird if they were in the regional dex but not actually in the region, so trading between the two will be enough. You only need to import or trade from other sources (ORAS/GTS) if you want the national dex completed.
You're playing my opposite games, in reverse order. I did Y, and now AS :) You are like Bizarro me, or vice versa! ha
So on the way to the ship, I just stopped at Barnes and Noble and bought this Pokédex. Man does this take me back, except it's about three times as thick as that first glossy Pokédex I bought back in the 90's, lol.
