Has she been taking a bottle at all up to this point? If not, there is really no need to introduce one now! Everyone has a different experience with the "evils" of bottles...some people just get lucky and don't have the problems.
We finished with the bottles right around a year, but I continued to nurse until my daughter was 18 months. I got "lucky" and had to be away on a business trip for 8 days...I decided to make the cut then. It was a pretty seamless transition--she asked for milk once two weeks after I got back.
She had been weaned from the pacifier, too...until the boob went away...lol. I let her have it back at night (which was the only time she got it before).
The morning session will probably be easier to cut than the nighttime. You should also consider taking steps to diminish your supply--cool cabbage leaf compresses or some people take OTC antihistamines (not recommeding this myself, but know OBs that have). Less milk will make it less soothing to her and you may be able to substitute some other type of comfort more easily.
Good luck...this can be such an emotional time for both of you.
