Theres a jig in FWW to level that size slab using a router.

Is the whole top cupped or does each half of the slab have a cup. Looks like the latter in the picture, but hard to tell. If its one big cup all the way across then you would probably have to rip it down and re-glue.

Might be worth it to rip out the pith and replace those parts with better wood if you have to rip it any way.

I wouldn’t worry about the knots if I could ever get it flat and re-glued and de-pithed. Would probably stay good a long time being oak.
