Not sure where abouts you're from, but in SA we have a 1800 24 hour parenting hotline that you can call and ask questions for immediate advice and support too. I would assume they have similar services interstate also .

P.S - I think its great you and your X are on amicable speaking terms!

P.P.S - I agree with Lulu - make your own support network, don't base it around your X...although I dareseay he could be part of it...

Good luck
