First pic if I'm seeing the one in the center is the support arm for the front diff. Unless you're having some 4wd concerns, I'd leave that alone.
2nd one belongs to the power steering rack.
Changing the 2nd, you might just change out your ps rack if its leaking out your rack boots. Atf leaks usually dont hit that area. Engine oil however, loves to travel.
Agree, it does look like a valve cover leak, usually people miss the rear cam block off caps, or don't remove and reseal them and the aluminium half moons. Here are what I usually get, double check your part numbers, this will improve steering response and feed back significantly, I usually order the sway bar kit at the same time..
