Yep, replace the plugs and wires. Also, stop smearing poo all over the boot...

Looks fairly normal. The brown on the boot is what happens to the rubber over the years...it's nothing to worry about unless the boot cracks...then the spark can arc to the head.

Same with the plug. The insulator gets hot and starts to discolor. Again, if it's running fine, I wouldn't worry about it. Replace that stuff if you want to.
