Help needed on 3d setup and upgrades

Hi

I am somewhat confused with the whole 3d transformation.

My setup is Optoma pj (that will be replaced for HD600X & 3dXL)

84" elec screen (possible upgrade)

Onkyo 606 (do I need to change this?)

PS3 and Xbox 360 also Alienware laptop with Nvidia 3d.

Am I right in thinking, I will need to replace my amp for one that has 3d pass through? I have read forums galore and its a bit of information overload.

The HD600X I believe has 1.3 HDMI input, but 3d needs 1.4, according to the forums. Will I need to change any of my HDMI cables and can you describe in simple terms the way I need to set things up.

Thanks in advance

Andy
