Debian signs the entire repository state, not each individual package. This has its pluses and minuses. The obvious drawback is that if you come across a Debian package outside of a repository structure, it is not, itself, signed, so you can't verify its validity (the exception is source packages, which have an independent signature).
You can to accompany the package with Release{,.gpg} (or just InRelease) files. Kinda fat detached signature. I do it when I download files like hd-media/boot.img.gz for installer.
The advantage of having a global repository state signature is that you can do things like this without difficulty. It has the mixed advantage and disadvantage that partial mirrors that modify the package set have to make their own signature and all clients that talk to them have to use different keys to verify those packages. Basically, the signing algorithm for a Debian repository rolls up all the hashes for each individual package in the archive and signs the whole thing (per-architecture, so you can do partial mirrors of only certain architectures without invalidating the overall signature).
I'm not sure what you mean here. Presumably you can have any subset of the packages and they will be happily verified against Release file?
