Thanks for the advice and support!

We are so nervous! And yes, you guys are right, we are probably really over-thinking this!
We asked about bringing Gidget, and she would like us to meet her first to see if our personalities fit before introducing Gidget. She is not far from us, so this method will work for us.
Topknot also brought up a good point about how their personalities would differ being in different homes. Do you recommend meeting on neutral ground somewhere instead? Or in our home?
We go this afternoon, so I will let you all know how we made out. Thanks guys!
