You can get owner and repo using the built-in vc.  bug-reference.el does
that, too, so have a look at `bug-reference-try-setup-from-vc'.
Essentially, it just gets the VCS URL and then the entries in
`bug-reference-setup-from-vc-alist' and
`bug-reference--setup-from-vc-alist' infer owner/project from that.  Of
course, the owner/project is just an convention of most forges.  And
also note that you could have setup many git remotes, so there could be
many "owners" and finding the "right" one is up to you.

As for the current branch, it seems there is no vc operation for that.
But `vc-git-dir-extra-headers' does it as part of its workings, so you
could copy this recipe if you want.
