Does My ferret need to go to the vet ?

She is 5 month old her name is Pepper and she is What I think is called Sage ? She has brown , white and grayish colours It does not really matter but i got her from a pet shop she came with papers Im not sure what they were since my mom took them but DOES she need to go and get shots ? what age will she need them ? might she already have her shots and does it matter if I remove her stink gland and does she NEED to be spayed ? she is alone and never sees male ferrets Thanks for reading !
