Ok so I have looked on the forum for the information but not finding exactly what I guess I am looking for so please forgive me if I am asking old question. Or please just give me the link.

2004 XF 158,000 coupe 6SPD grey color

Knowing that I plan to change the oil , get new tires and fresh battery. I wanted to know what other things I should do as far as basic tune up work on the cross fire after I pick her up. When I change the oil what filter to get ? Do I need to replace oil plug ? And what's a nice set of tires to get. It does not snow where I live so no issues there. Just trying to get all my stuff in order once I pick her up. Thanks again for the fast responses from my last post.
