clicker training is excellent! i use dogwise to find training books and tools (by subject is great).

the nibbling, pawing, etc. is pretty easy to fix. when she bites, just yelp outloud ("ouch") and stop playing and ignore her for 10 minutes. same with any other behavior she does, like jumping on you or pawing. ignore. no talking or eye contact or walk out of the room. this is called "negative punishment" because you are taking away something she wants, your attention.

wrt potty training, there are great threads here on the subject but a schedule, diligence and setting her up for success are the key. also having treats right where she is supposed to go potty so you can immediately reward her.

barking can be an issue to deal with. unfortunately i can't tell from your email how her barking is: normal communication? wanting attention? or being reactive or some combination. this is where a good trainer will help you and teach you how to use the clicker to reinforce fiona to listen to you and respond when you say "hush" or whatever command.

hth for the time being! there are some excellent trainers on the board that taught me a lot and can provide more pointers.
