Kit looks great, but I spotted a bit of a problem. You have those beautiful wooden stakes, but nothing to really pound them in with! 3 crosses may be a bit overkill, why not convert one into a mallet?
If you want to turn one of the crosses into a mallet, I suggest bashing the ends in repeatedly so it looks used/worn (as if they have actually been pounding stakes)
That said, something like this:
With a few symbolic carvings, maybe a bit of leather wrapping the handle (nothing like fighting off legions of he undead only to end up with splinters in your hand!)
One thing to keep in mind is not just making the objects look old, but making them look used. Think of how repeated use chips/cracks/wears/stains/deforms an object, based on its intended use.
Keep up the good work!
