Hi Cbelle! Yes, you are right, it all can be very confusing. Unfortunately there is just not one formula or equation that works for all. Many of the things that you hear and see are general guidelines that work for many but not all. Or that work for many as a starting point but once they have already done these things would need something else to continue to see results or that work for many but need to be tweeked some, etc. Same goes for nutrition. Depending on your genetics and lifestyle, your nutrition requirements will vary.
To answer your question directly, generally speaking, a combination of both weight training and cardio is recommended for body fat loss since both play an important role in stimulating and boosting ones metabolism. So with this information, it is best to look at what you are doing now, evaluate it, and decide where to make changes to enhance your goals.
For your fitness routine, if you are happy with the amount of strength you have, simply change your exercise order around or substitute some new exercises in place of others. For cardio, add a new form of cardio, something completely different than what you are doing now, to get muscles working in new ways. But remember to ease into the new activity since your muscles will need to get acclimated. Or you can try adding a day of cardio, or high intensity circuit workout, or interval workout, if it is something you are currently not doing. Just some examples not rules ;-).
For nutrition, contact a local registered dietician and ask to have a consultation. You can tell them of your workout structure and they will help you create a nutritious customized food plan to meet your energy output. This will help eliminate some guesswork for you.
Good Luck!
