First of all, I would like to say that answers to your questions depend
on a filesystem type. And actually, that's why it is up to each filesystem
to "answer" on them via dentry_to_fhandle/fhandle_to_dentry specification.
AFAIK a lot of "good" filesystems ( e.g. ext2, iso and some others )
are capable of providing dentry_to_fhandle/fhandle_to_dentry interface
the way, that:

yes

yes.

depends on fs. but I guess yes.
