Gosh, you have bitten off a lot. New to 3D printing and new build it yourself machine.

In my experience:
You should print out a Benchy and post up some high resolution photos of the results. You will get your best response that way.
Also, ghosting is usually a symptom of poor rigidity. Make sure your belts are tight and it will reduce the ringing in the mechanics that causes the ghost image.
Start by testing the mechanical things first. Straight lines, extrusion temperatures, bed adhesion, testing should come before stuff like pressure advance and retraction distance.

Just my $.02
