Good advice from some savvy people above. Fluids first. Take a sample of the oil and send it to Blackstone labs

This will give you a decent idea on the condition of the engine and some piece of mind. Unfortunately, unless you have the service records, you will not know how many miles are on the current oil cycle. So, after the oil change, change again after 3k miles and send in another sample.
Filters, 1 do not use Fram, not a good track record. Wix also did not have a great record with several issues reported here on MUD. If you search the net you will find a oil filter test/comparison. While it wasn't the best, it was readily available so I use the Mobil 1 filters. Religiously change the oil, type of oil is a huge black hole and will create a huge debate. If you stay on top of the oil changes any major manufacturer's product is good. No product is good if you neglect it.
Fuel filter probably should be changed as well. PITA to get to though. I know the others have said don't worry about the rubber but, as a piece of mind just check them, especially if it is the PHH. If the original clamps are on it, change it now.
Remember not to mix coolant types when changing the coolant. If it is green stay green, same with the red.
Get a cheap scanning tool and an app like Torque to read it. Can save time later and give an instant diagnosis.
Finally, read the FAQ on the site. Get to know the new girlfriend inside and out. Treat her right, she will return the favor.
