Welcome. I would give her a walk before taking her home and keep her on her leash while you show her your home. If the yard is fenced I would let her off leash to play and explore.
There is a lot of good advice on this forum about bringing a pup home. My best advice is to try to catch her doing good things. Give her lots of praise and exercise. Tired dogs are good dogs.
If you can get her into an earlier class or do some private instruction before Feb. it might help as this is your first dog.
