Here's some quick and dirty custom CSS for hiding the resize link and making the favorite link bigger, maybe that will be good enough. Paste this into the custom CSS box under your account settings:
/* Hide the "Resize to window" link on /posts/1234. */
#c-posts #a-show #post-options > ul > li:nth-child(1) {
display: none;
}
/* Make the "Favorite" link bigger on /posts/1234. */
#c-posts #a-show #post-options > ul > li:nth-child(2) {
font-size: 200%;
}
Actually changing the order of the links would require a userscript.
