As to the worming/flea question ask your breeder when it was done and when it's next due. Elfpup came with explicit instructions on when he was due a treatment and what to use. She also sent me a reminder text just before it was due.
Take her to the vet in the next couple of days for a check over (your breeder's contract has probably stipulated this anyway because if she has any health issues they need to know asap) and the vet will be able to check flea and worming status and get you on a schedule but it tends to be monthly for the first 6 months.
Our vets has a petplan which includes worming and flea treatments in their monthly charge, as well as injections etc. I'm sure if they do the same at your vets they'll let you know. We go monthly for weighing and the flea treatment.
