Yeah...I hate to tell you this but the biting is pretty normal for a child this age. She will bite and get bit a few times in daycare before she learns to cope with her frustration in a different manner.
The best tactic I found was redirection. Defusing the situation before it gets to the biting point and positively reinforcing that "teeth are for food" "teeth are for chewing" "teeth are for smiling".
You should also ask the daycare what sort of discipline they are using...consistency is key. I didn't resort to biting her back until she was two. By then, she had the verbal skills to tell me what was wrong and understand that she was being bit because she bit me.
Licking? My two and half year old licks me but it is because she thinks its funny and she tells me she is a puppy.
I've always restricted the use of the pacifier...to the car and bed when she was younger and now just to the bed. She understands that if she wants the pacifier that she has to be lying down. Suckling is still a comfort to children this age and I find that it can help defuse a tantrum if she gets a little quiet and comfort. She is old enough to understand that she needs to lay down--at this age, they would rather be playing so you will probably find that you get to the night time only very quickly.
Good luck. My daughter still uses hers about 50% of the time to sleep at night, but most nights I can pull it out and she does fine. I started poking holes in them a few months back--she still likes them just fine. I tried cutting them back gradually but that just caused a tantrum. She uses it so little that I don't feel like either of us need to lose sleep.
