If the guy was convicted on State charges, then Bush has no jurisdictional authority to pardon him.

Not true. The Presidential power to pardon is absolute.

Thats what I thougt. Very curious to know the answer. It does seem that the pardons you hear about were for scumbags that were convicted in federal court...
