Yes, the packages do go on sale and yes, you can make resturaunt reservations more than 90 days ahead (or at least did in 2003, when I went last). The only problem I had was that that was before they announced definitely who the speakers would be for which night. So I made my reservations for a certain date not knowing for sure who'd be speaking. But I decided to take that chance and not wait-it was a good thing, too-I had my heart set on the package including R&C, being there for Illuminations, and I might not have gotten it had I waited.
