I believe that this link should answer your question about the structure of the inode. The inode tables should reside in kernel space, but am not too sure about that. For the third question, yes a file residing in one filesystem will have a single inode number unless you change it yourself. (You cannot directly change an inode number for a file. You have to follow a procedure. See below.)
Code:
# ls -li a.out
  8230 -rwxr-xr-x   1 root       sys          24576 Jun 19 08:10 a.out
# cp -p a.out a.out.tmp; mv a.out.tmp a.out;
# ls -li a.out
  3268 -rwxr-xr-x   1 root       sys          24576 Jun 19 08:10 a.out

NAME
matchpathcon_checkmatches, matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether any specification index has no matches with any inode. Maintenance and statistics on inode associations SYNOPSIS
#include <selinux/selinux.h> void matchpathcon_checkmatches(char *str); int matchpathcon_filespec_add(ino_t ino, int specind, const char *file); void matchpathcon_filespec_destroy(void); void matchpathcon_filespec_eval(void); DESCRIPTION
matchpathcon_checkmatches() checks whether any specification has no matches and reports them. The str argument is used as a prefix for any warning messages. matchpathcon_filespec_add() maintains an association between an inode ino and a specification index specind, and checks whether a conflict- ing specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two specifications based on their order in the file context configuration. Returns the specification index used or -1 on error. matchpathcon_filespec_destroy() destroys any inode associations that have been added, e.g. to restart for a new filesystem. matchpathcon_filespec_eval() displays statistics on the hash table usage for the inode associations. RETURN VALUE
Returns zero on success or -1 otherwise. SEE ALSO
