mom this is common and normal. completely age appropriate for your little girl.
www.askdrsears.com is a good resource. you never want to use the cry it out method on any baby under the age of a year (or abouts; you will notice a difference in cry when they are old enough to 'wait' a bit)
elizabeth pantley has a GREAT sleep book, as does william and martha sears. the latter had 8 children of their own, so they know their stuff. :D
just trust your mommy instincts! there is NOTHING wrong with nursing her to sleep at this point. dont let ANYONE tell you otherwise. wait a couple months, around 4 months elizabeth pantley talks about the 'pantley removal method' where you nurse and baby starts falling asleep, you break the suction, and remove her, and when she starts looking for it again, you give it back... what this does is eventually helps her learn to fall asleep without the nipple in her mouth... but NEVER refuse her the nursing or sucking, just remove it and give her a second to see if she can calm down on her own. you might be surprised how quickly it works.
but again, dont start trying to do that until around 4 months or so. check out elizabeth pantley's book. i forget the exact title, but its a pretty popular one.
other things that might help you: a white noise machine, or the cd that i bought "for crying out loud" that has 8 tracks of 9 minute white noises like a washer, car windsheild wipers, a noisy restaurant, and my son's favorite the vacuum! babies are used to a LOT of noise. my son required our vacuum running all night long in order to sleep :P we found that cd and it helped tremendously! :D
anyway. that might just be the thing right there is to get a white noise machine or some sort of white noise cd. :D its awesome. :D

cosleeping (baby in same room) is a VERY good idea; prevents SIDS, and gives you the ability to get to baby at night before she gets so upset that she cant get back to sleep peacefully.
bedsharing is another safe and effective option. it worked so well for me, i cant imagine NOT doing it! :D after all, someday not so long from now, they will be grown and you will have to drag smiles, hugs and kisses out of them at all... :D
