Calling all cat people. Need advice!

I will be welcoming a new furball soon. She’s four, coming from a family who love her very much and have taken very good care of her. Unfortunately, their situation has changed and they are trusting me with her.
It’s been about 8 years since I lost my boy and I’m a little scared to take her on. What can I do to make her transition easier? I’m not crazy about closing her in a room for a couple of days. Would it be ok to let her explore on her own? Should I get some feliway? Bribe with snackies? Roast a chicken to entice her?
You guys love your kitties so much, I know you’ll have some great ideas. Thanks so much.
