Bigtime. The only things it couldn't learn would be things base classes get at level 19 and 20, or from PrCs (thank god).

Plus, casting any two spells as a standard action? Or THREE? Cast three 1 round casting time spells right there and everyone will want you dead or worship you.

...also, you're missing a class skills list.
