Hello and welcome to WPF.
So, let me see if I've understood your request correctly....
To paraphrase, you want to take pictures of a blue car, but you don't know what sort of lighting it's going to be in, it could be anything between very bright and very dark, you don't know if it's going to be static or moving, the kind of results you are looking for are "various", and you want us to tell you here which settings to use in the camera to give you "the best results". Hmmm, that's quite a tall order.
Firstly, read the "sticky" threads at the top of this sub-forum:

That will give you some idea of how the different settings will affect the result.
For the moving shots, you need to fully understand the different autofocus modes you have on your camera. Read the manual and then experiment with the different AF modes on a range of moving objects. Practice your panning technique, moving the camera to keep the subject at the same point in the frame as it passes by -get your mate to drive up and down the road at different speeds as you follow his movement through the viewfinder. Practice is the key here. Learn what the different settings do by reading the threads I've pointed you at and also fully understanding the AF modes on the camera, then get out there and practice.
Regarding the polariser, it will reduce reflections, but only in certain lighting conditions, and you know how to use one - practice is again the answer. Describing how to use a polarising filter via written text is a bit of a non-starter, you have to be looking through the viewfinder to see what's happening as you rotate the filter.
Hope this helps.
