The first is the manifold heat riser tube. Dorman used to carry replacements in their Help section. You can get them at the junk yard but most are pretty ratty by now. Just measure the diameter and find one to fit. The second is a valve cover gasket leaking. It looks like you have cork gaskets and those break down over time. I usually replace them with rubber gaskets with a little black RTV for sealing. Over time these get beat up. The RTV will make sure it doesn't leak. One caveat though, often I've found someone pried on the cover and bent it. Find a had flat surface, preferably metal like a bench vise and use a tack hammer to tap it back into shape. That's how I managed to fix repeat leaks when I ran a shop.
