There's absolutely no need for a baby who's turning one to stop drinking from a bottle. The "one year" rule was just something a bunch of formula company execs dreamed up anyway - it was a way to get people to use formula longer originally. Now people think it's based on something real, not just a bunch of guys sitting around a boardroom.
Anyway... if she's small for her size, do whatever works for her and your family. If that means four or five bottles a day until she's two, so what? If she doesn't do well with solid food, keep her on breastmilk or formula for another six months. Just make sure she's getting good nutrition and calories. Formula is WAY more nutritious than cow's milk, so before you switch her to milk, talk to your pedi (and feeding therapist if you have one) to see if she's ready. We didn't switch to cow's milk until my girls were 18 months old because they were small. And we kept all bottles until they were 15 months, and slowly dropped the bottles until we dropped the last one when they turned two. They're now almost 5 and drink from cups just fine, eat all table food, etc. You'd never know they had a slow transition off the bottle.
(about the pacifier - drop it whenever you're ready. If she's developmentally a one year old, her size shouldn't matter for when you stop allowing her to use it.)
