the extra feat is definitely a good choice.

too much con is probably pointless (it can even stay at 10) and certainly more than 16 dex would be a reasonable choice, if not maxed-out, then almost (and i mean 19).

wisdom might also be unnecessary, especially at the beginning, since the spells are gained late and often prove useless at that point.

some decent int (14) sounds cool since the build is rich on possibilities as far as class skills are concerned.
