I agree with Winder - old valve cover gasket. Very common. And the head gasket is actually below where you are probably seeing the leak. The bolt doesn't go through to an oil passage, so that isn't it.
Replacing the valve cover gasket is pretty simple - about an hour of work, assuming the old gasket is a pain and bits of it stick to the head and valve cover. If the old gasket comes right out, it's a half-hour job. Two tricks - 1- the bolts for the valve cover torque to 11 ft-lbs. Make sure you have a torque wrench that goes down that low - many don't. And 2 - use a good anerobic sealer on the gasket. Some folks have had good luck with just the gasket, but I haven't. I use stuff like Loctite 518, but any good anerobic gasket sealer will work. Although the Bentley manual shows running it around just 3/4 of the valve cover, I run it completely around.
After you're done, clean the area with some paper towels and degreaser. There is still an oil film there from the leak, and if you don't clean it, you'll be convinced that your new gasket is leaking.
As to the exhaust manifold bolt. The right solution is to use an easy-out on it. That involves drilling into it to make a hole and then inserting an easy-out (reverse-threaded screw). Works great when it works. If you've never used one, I don't recommend learning here. Access is tough, and it is hard to drill in straight. Break off the bit or the easy out, and it's a lot harder drilling out the tool steel. I'd bring it to a shop. I'm used to seeing one bolt broken, but two is a bit new. Is it possible that one bolt broke and the other is just not there? Can you see thread? If so, you could get away with just inserting a new bolt.
