Yes.  These are correct:

/* get a URI from the file chooser and turn it into a GnomeVFSURI */
char *str_uri = gtk_file_chooser_get_uri (chooser);
GnomeVFSURI *vfs_uri = gnome_vfs_uri_new (str_uri);


/* Get a filename from the file chooser and turn it into a GnomeVFSURI */
char *filename_on_disk = gtk_file_chooser_get_filename (chooser);
GnomeVFSURI *vfs_uri = gnome_vfs_get_uri_from_local_path (filename_on_disk);


/* Get a filename from the file chooser and display it in a widget */
char *filename_on_disk = gtk_file_chooser_get_filename (chooser);
GError *error = NULL;
char *utf8_filename = g_filename_to_utf8 (filename_on_disk, -1, NULL, NULL, &error);
if (utf8_filename == NULL)
    g_error ("Could not convert on-disk filename to UTF-8: %s", error->message);
else
    gtk_entry_set_text (entry, utf8_filename);


/* Get a filename from the user and turn it into a GnomeVFSURI */
const char *utf8_filename = gtk_entry_get_text (entry);
GnomeVFSURI *vfs_uri;

/* The long way */
GError *error = NULL;
char *filename = g_filename_from_utf8 (utf8_filename, -1, NULL, NULL, &error);
if (!g_path_is_absolute (filename))
    g_error ("Please type a full pathname");

if (filename == NULL)
    g_error ("Could not convert UTF-8 filename to on-disk representation: %s", error->message);
else
    vfs_uri = gnome_vfs_get_uri_from_local_path (filename);

/* The short way */
vfs_uri = gnome_vfs_make_uri_from_input (utf8_filename);


We should sprinkle all the relevant docs with examples...
