1. You can NOT naturally carb or force carb in a growler, there is a high risk of it exploding. There is a variable as to what the growler is made of. If the growler is stainless steel it may be able to take the pressure but as a rule glass growlers are NOT good for carbing that way.
2.A bottling wand will not carb up flat beer. It is only to bottle already carbed up beer, usually from a keg. The counter pressure helps the beer stay carbonated during the transfer so you do not end up with flat beer from the transfer and capping.
3. A carbonator cap is not designed to be used on a glass growler for the same reason listed above in "1", they attach to soda bottles (do not use rootbeer). You can buy them from a LHBS or online retailer and there is a DIY if you search for it.
