About rear wing changes:
End plates are not affected?
After seeing the first pics of new '09 spec rear wing for F1 which looks absolutely horrendously out of proportion...

...new wings on LMPs might have a bit similar effect to looks. I mean take a look at some picture of LMP and imagine 20 cm cut from each side. With smaller endplates might actually look more aggressive.
I'm tempted to do a photoshop mockup.
