Hey Hal !
Welcome to Montenegro !
I have made the same move, from France, in 2008 and very happy with the decision. Montenegro is wonderful, beautiful and extremely safe 
It seems you know the country already since you already picked the area where you want to live!
I am happy to send you a few contact to help you with residency in particular (one of my business partner handles accounting, taxes, legal and residency permits alltogether).
For banks I would say Hypotekarna is the "least bad" from what I have heard...
Laywers, really depends what you need them for.
Feel free to send me a dm,
Cheers,
Tsarina
