For the oil, I would switch to synthetic since your engine is rather young. Mobile 1 is fine. You can either use a Mobil 1 filter or a K&N filter for the best performance, both are made by the same company, champion labs. The Mobil 1 filter has finer filtration but the K&N flows better. Mobil 1 is better for the daily driver. As for your question about the ATF and such, I believe the answer depends on whether you have a V6 or an I4 engine...
