I have already done the grill mod on one of my 219's. i guess my next question is how do i get into the body to take a look-see at these resonators to see if i am capable of getting them off.

Body comes apart into two halves. Take the top half off (unscrew the "base" that holds it to the stand adapter, remove the one screw that holds the "top" on). Now you will be staring at the capsule. You can remove the PCB upon which the capsule is mounted by taking out the little standoff IIRC, then you will have the mic in three pieces: two sides of the case, and the guts. I imagine to do the grillemod, you had to disassemble it like this.
The "resonator" is the black or gray plastic round thingy on the capsule secured around the edges with a coupla teeny screws. It has holes in it that are actually kind of like tuned ports to resonate certain frequencies and make the mic a little brighter at the expense of transient response and phase detail I'd guess.
The problem is that the center electrode wire (with a little lug attached to a screw in the center of the diaphragm) runs through the hole in the middle of the resonator. So you can remove the little screws that hold the resonator on, and then it will be loose but still can't be removed with the wire running through it (the wire obviously holds it on... will be very obvious once the mic's apart). So you have to either (a) remove the screw securing the center electrode from the diaphragm, slip the resonator off, and then reinstall the screw/electrode [totally NOT recommended], (b) unsolder the wire where that electrode attaches to the circuit board, slip the resonator off, and re-solder it back [slightly more recommended], or (c) use a wire cutter to snip the resonator to bits so it can be removed from the wire without removing either end of the wire.
I don't remember if there is a resonator on both sides of the capsule or not. If there is, then the rear one is easy to remove, there is no electrode to take off, just screws.
Put the screws back where they came from after you remove the resonator. Don't poke the screwdriver through the diaphragm. This is a whole lot harder than you think. flat-head screwdriver slips out of those slots in the screws very easily!

also do you know how to dampen the body so i don't get the "boink" sound when it's moved?

yes, jam it in one of these
http://tensimount.com/actually it won't dampen the body, just lessen the odds of it being moved. Some folks have put silicone caulk inside the mic body to dampen it. The grille mod will most likely fix the "ding" since it's the ringing of the grille bars that is so easily picked up by the mic capsule. Easiest thing to do is just mechanically isolate the mic while it's in use with a shock mount. A MK-219 just barely fits in a tensimount.
