On the custody question... divorce is like a big game of "chicken". You just need to <act> like you are going "all the way" to trial unless you get your way.
You come out and demand full custody. Be emphatic. Make her believe you will accept nothing less. Then her lawyer will tell her "either give him full custody, or fork over a $20K retainer". Will she really pay the money? I doubt it. She will roll.
