I suggest to use your AES credits for other airports. All FSDT airports already have animated jetways anyway, and they are designed to be integrated and used with GSX.
The only version of KLAS we ever released for FSX/P3D it's V2. It's called that way, just to not have users confusing with the old Cloud9 version, which was an FS9-only product.
Can I remove the static containers next to the aircraft.
This is what GSX does automatically when you select a parking from it, since it's one of the benefit of having it integrated with the scenery. Also, KLAX uses several custom pushback routes for GSX, so you better use GSX on it.
