what you need is a hockey, or football gear bag. they are big, and you can fit a lot of stuff in there. also, they generally have wheels, so you can pull them behind you. you can easily fit all the smaller parts in there, and for the chest, i would just use a clothes hanger and carry it by hand, or just hang it on the handle of the bag. also, wrap every part in a piece of cloth, so they dont hit each other and wear off the paint.
this way, you need 2 bags for 2 sets of armor, hang the chest pieces on the handle, and pull the two bags behind you.
