found this link that says that licking means "i love you and trust you" the link also has some other facts i found helpful http://rabbitresource.org/care-and-health/behavior/how-to-speak-rabbit/
Sue it very well could be... for chewing on carpet spray vinegar mixed with water on your carpet.. not to much vinegar or your house will smell like it... buns dont like the smell and will not lick or eat anything with vinegar...
it is possible that she is pregnant.. keep watching her.. if she is pregnant gestation is about 31 days.. if i were you i would take her to the vet and get her checked out... my bunny silver was 3 months old when she has her first kits and they did not make it but she made it through...
Since Silver had her babies she has been licking me every time i pet her... why would she do this??? she has never done it before.. could it be the motherly instincts in her???
today they are 15 days old.... they are jumping out of the nest already and are sooooo adventurous and cute... I had them out with dad and he actually attacked me when i tried to pet one...
