I nursed my eldest for 17 months, and my baby is still nursing at 11 months. Both were sleeping through the night by ten months.
There is no reason nursing can't be part of your routine. Nurse until the point of drowsiness, and then brush teeth while baby is drowsy. (If baby is still alert, make something fun but bedtime related part of the routine - both of my daughters think it's fun when daddy lifts them up to turn the light off themselves. The four-year old gets a bit of a swing in the lift, but it's still lights-out time.) Then kiss, hug, tuck-in, goodnight.
When my oldest started showing signs of wanting to wean, I started reading books out loud to her while she nursed in the evening. We sort of transitioned from nursing to storytime slowly that way.
I've heard a lot of people seem to use the cio method as just leaving the child to cry. We never did that - we did do Ferber, though. Check out Solve Your Child's Sleep Problems by Ferber. It takes three days of consistency - use the same routine for naps and bedtime.
Just offer water at night. I'd try cutting out one nighttime feeding at a time, though, and not all of them at once.
If bottles are a problem, go out somewhere this weekend, and let Daddy give the bottle with breastmilk. She won't take a bottle from you - you've got the source, why should she?, but she might take it from Daddy.
Once the bottle is familiar, then introduce it with water. We had to do this with my oldest - she just needed to realize that bottles contained edible stuff.
And I'd definately try naptime in the crib before bedtime. Let her experience the crib - play in there, put a music box in there - we have a mobile by TinyLove where the mobile part detaches and the base becomes a simple to use music box. There were many times when both children haven't napped during the allotted naptime, and played a little instead, but some quiet recharge time is still valuable.
Having said that, every family is unique - you'll figure out what works best for you. Hang in there, mama!
