If I migrate from APS-C to a99, which lenses will work?

I am considering replacement of my a77 with an a99, and wonder which of my lenses will work. Specifically, I am concerned that some lenses such as my Sigma 8-16 have a crop sensor imaging circle which does not cover the entire full frame. I am also equally concerned that auto focus or other lens automation will be reduced or eliminated entirely with this migration.

My specific A-mount lens collection is as follows:

Sigma 8-16

Sony CZ16-80

Sony 18-250

Sony 70-300G

Sony 35mm f/1.8 SAL35F18

Will any of these permit true full frame use. I understand that the crop factor which I ezxperience on APS-C bodies will no longer apply, but I am asking specifically which if any of these lenses will continue to have full automation, and also have coverage of the entire full frame sensor area.

Also, are there other issues I have not adddressed, such as very sub-optimal focusing given the way the a99 focusing works versus my current a77?

Thanks for any guidance.
