Rust on Bronco tailgate...

My 1984 Bronco XLT has developed some nasty rust bubbles on the tailgate.
I would like to know what I can do (I have read a couple of posts in this section already) to halt the rust spreading.
I am thinking of sanding off the paint and rust to get back to bare metal (i hope there's no rust pinhole or hole at all beneath) and then applying anti-rust formula and a little filler and touch-up paint.
is this a sound idea? or does anyone have any suggestions otherwise?
also, what would be the best color to match the standard bronco reddy/orange as shown in the photo?
here's the offending area
thanks guys, any help is greatly appreciated

I'm going to give spray-paint a miss, not confident in my ability to prevent runs or layer thickness.
foam-brush auto paint will be the trick I think.
this will be the first time I have attempted any kind of bodywork on a truck. hope i dont botch it.
it seems whoever had this truck before me was a real loser and touched the back up to look normal only for resale purposes. >

in some places the body filler goes 1 inch deep and it's looking like I'm going to have to cut the whole bottom tailgate section off, and get a new part fabricated and welded on.
