Are you linking to the shiv correctly?
<!--[if lt IE 9]>
It doesn't seem to be where you are looking for it and may explain the footer problems.
I haven't had a chance to look at the animation but I'm guessing you will have to completely revise it for ie8. Just on my way out now so will have to look tomorrow.
As an aside I notice you haven't added the fixes I gave In this thread yet.
