I would let her cry for a little bit and go in to calm her every 5-10 minutes (sooner if she is REALLY SCREAMING and you are afraid she is going to make herself sick) google and read about the furber method
here is my experience:
Our daughter is 6 months old, she has been in her crib for about 2 months (she took her naps in there sooner) She used to cry and fight bed time then I found a blanket called a "swaddle me" and she LOVED it..when she out grew it I had to make my own because she refuses to sleep without it. It gives her that same cozy feeling...i also put a blanket on top of her and tuck it around her sides so she has that extra support at her sides that her bouncy seat gave her (that is the only place she would sleep as a new born) But even with the swaddle me she would do the same thing as your little one...wake up 30 minutes after going down every night....i would go in to comfort her, give the pacifire back, etc...and the fight would last for hours.....finally last week i gave in and let her cry it out (only going in a couple of times to give back the pacifire) and she cried off and on for a little under an hour, and we haven't had a night of crying sense!
Also i recomend a battery powered mobile with a remote so that it can be turned on without her seeing you (this was a life saver when we decided that we had tried everything else and just needed to let our daughter "cry it out")
