Let me give some suggestions for the part 2.
Most of the clips in our project featured LFE & surround, music & visuals.
Basically most clips fell into very few categories:
Example for LFE it was mostly explosion & fight scenes.
For surrounds, it was mostly Jet plane scenes.
Visuals, mostly pixar films.
I recently found that while watching that what was lacking was a diversity for the LFE, sometimes watching a demo disk full of explosions can shake up your head after some time.
So I suggest:
Motor engine noise scenes from Fast & the Furious (DTS) & Torque
Train engine sound (From DD trailer & Polar Express)
Drums (Drum Line end sequence, astig!)
Visuals (Final Fantasy advent children! when its out)
