Fixing oil leaks on '02 4.6is w/ 133k

Monday last week I picked up a 4.6is w/133k on the clock. Test drove it and everything is great with it mechanically and appearance wise, both inside and out. Has brand new tires and has been garage kept. For a car with this many miles, I was pretty amazed how good it looked. I'm replacing the headlights with DEPOs and putting on Sonic LED tails.

Couple of pic of the ride after I got it home:





I did notice an oil leak from looking at the underside of the car before I purchased it from a private seller. I'm still hopeful that replacing the cylinder head gaskets will fix most of that.

After sitting a week in my garage (I drove it straight home, so I have personally only driven this truck 20 miles since I got it last week), I'm seeing the following oil drops on the floor:



And a shot of the belly where the leaks originate:



I've been doing a lot of reading here over the last week since I purchased the truck, so I figured the first order of business is to pull the cylinder head covers and replace those gaskets. Here's a shot of the TB as I was taking stuff apart. I think the TB plate looks pretty good and clean.



So here's the right cover just before pulling it. Notice how the paint has peeled. Is that normal for this age and mileage?



Cover off:



Whole engine. Notice how the left cover has as much peeling if not more.



Cover by itself. I'm thinking of painting it. Any recommendations on prep and what paint to use?



Here are the coils. All were bone dry, so at least the inner gasket was not leaking.



Looks like one of the coils was replace a few years ago:



Well, that's as far as I gave gotten so far. Any suggestions on what else to do to the engine while I have it apart?

Oh yea, I'm planning on flushing the coolant and putting in Evans. Put the sticker on already.
