That's it. The one pictured is an old style housing. They moved the bleeder into the line. As I recall that is also an item you want to go to the dealer for.
Absolutely. They are in aftermarket, but they are all made by Dorman (marketed under other brand names in some cases), and they don't last long, so get it from the dealer.
You will want to get the outlet housing *and* the metal pipe because if you only get the new design housing and re-use your old pipe, you will be without a bleeder. IIRC, they have one part number that is just the outlet housing, and another part number for the pipe, and a third part number that includes both parts (that may have changed) - but in any case, get both parts.
Get the pipe-to-outlet housing o-ring too - it probably comes with the parts, but not 100% sure of that.
There are four screws that attach the outlet housing, *but*, unfortunately, you can't get the two rear screws out without at least loosening all the screws holding the plenum down so you can raise the plenum up enough to get those two screws out.
Not required, but I suggest that you totally remove the plenum because a lot of dirt and grit tends to settle under the plenum around the gasketed area so that when you lift the plenum up, some of the grit falls over on top of the gaskets, and you'll want to clean (vacuum) that off. I'm not saying that it won't seal if you leave the grit, but there is that risk. Consider also getting new plenum gaskets - they're very inexpensive - go OEM or Fel-Pro.
Take the opportunity to flush the cooling system and put in all new full-strength G-05 antifreeze diluted 50/50 with distilled water. (G-05 would be Zerex G-05 (yellow), Chrysler/Mopar 5 year/100k mile (orange), or Ford/Motorcraft VC-7-B Gold (yellow, comes in red container).)
