Darling K.;
First of all, you are FANTASTIC. what a devoted lady. you are doing a great job, you have your whole heart, and your whole brain, invested in this, and you're looking for compassionate answers, and that's all you doing everything right.
have you checked out the Dr. Jay Gordon website for "family bed"? he really supports co-sleeping and has a very humane plan for helping OLDER babies learn to sleep alone.
but, that said, he focuses on the older babies. your baby is still SO little. if you are finding that everyone is getting the most sleep keeping her in the bed, i would encourage you to stick with that. i know a bunch of moms of kids who are over 2 who moved the kids successfully from cosleeping into a toddler bed with no crib in between. many of them used the GOrdon method, the Pantley which you have read, others have had success w just thier own sense of responding to the baby, which sounds like you and your instinctive inclinations.
my kids are 3 and 18 months, and i did not co sleep them, but i did try! but my kids just were into thier cribs i was lucky; however, i did NURSE my son to sleep until he was almost 3, and he only just weaned a few weeks after he turned 3. and it was EASY because he was old enough to talk about it and lean on other ways of being close to me for comfort and for going to sleep. my point is, your baby will not sleep in your bed until she is 6. don't worry.
as for going to sleep at night after 8 yourself, sadly i do not have adivce other than to say, if you hang in there with her, going to sleep early, through the transition of you going back to work, i would bet big money that she will ultimately let you nurse her to sleep and leave her there; either in your bed with bed rails which you can find on line or even nurse to sleep and get put into her own crib.
the trick is HUGE amounts of patience by you. don't believe any of these BS systems that say you can make these changes in a week; it may happen like that for a couple of families once in a while but it's not the norm at all. changes here at our house tended to take months where sleep was concerned. in fact here is the link for my blog posting about sleep;

if this doens't make you feel better about YOUR life nothing will! LOL!
hang tough and good luck, it does get better; my daughter now nurses to sleep, gets put in her crib, and usually wakes up not more than 1x per night and my son cuddles to sleep and stays there all night. you will survive and it will all get better.
lotza luv
