If you are attending as a guest then you may wear whatever pants you want. If you are afraid of being out of place you can always ask the bride or the groom. However, if you are part of the wedding party you definitely should run it by the bride or the groom.
No.
black
black dress shirt black dress pants and polished black formal shoes
Nothing. Don't wear them!
a big jacket which was black, black pants and loads of bages and stuff. looked pretty hot.
A black tie. Assuming that the shoes will be black.
You could wear a dark blue or black suit to a 5pm wedding. You could also just wear nice pants with a collar shirt.
ya
yes, of course you could, but remember, it's your decision what you wear. It, also depends on what you thinks looks nice together. A general rule of thumb is black does not go with black. Some may do it to hide the shape of their body, and others may do it to mimick the Johny Cash style. If that is your style then I suggest adding a little color to it through the accessories. Hope this helps. :)

Any color if your pants are all black
no, it does not. a light colored jacket or a black jacket will go better with black pants.
