Is it possible to get a router’s IP address from a Wi-Fi signal without having to connect in, given that it's broadcasting Wi-Fi, but requires a WPA password?

You can't:
And it's simply, IEEE 802.11 and variants work in Layer 2 and Layer 1 in the OSI Model.
To be able to discover another host using UDP datagrams, TCP packets, or even ICMP, you need third-layer connectivity.

I do not believe so. You can find it's MAC address but I don't believe you will get the IP address until you have successfully connected.
