FIRST REPLY!!! 
Congrats on the wedding Vod.
Don't have any ideas about the cod, since I dont have one in my armor (target is too small to hit
) I'd say just buy a cheap one from the flea of bay.
As for pic's you can host them, the use a simple HTML code to post them... Sorry I don't know HTML, but have used HTML code from free tutorial sites, you could do that.
As for the arms and shins, you could use a small oval trash can like the one pictured below.
I didn't sand my armor, I used Krylon fusion, then layered other paints.
