Are my points earned on my Cabelas credit card good at Bass Pro stores?

Yes they should but call and ask

Yes you can redeem your Cabela's credit card points for Bass Pro gift cards. And vice versa. And you'll still get the 1% if you use your Cabela's credit card points at Bass Pro

Yes

Not at this time but reportedly they will in the future

No. That aspect of Cabelas and Bass Pro are still separate.
