There are others better informed than me, as I am new to this machine myself. But untill you get more answers, I would suggest the following. Stitch leangth 2.5 to 3. Pressure would be dictated by the thickness of what your quilting and how thick it is, so I would start in the middle where the green area is and start adjusting from there.
Now thread tension is trickier. That you should be able to judge by doing different samples of straight stitches until you have a proper distribution to you upper thread and your bottom thread. In other words, your top thread shows only on the top and doesn't pull any of the bottom thread up to the top, and vice versa.
You have two tensions to deal with, your bobbin tension and your upper tension. If you can't get it right just tweaking your upper tension, than you need to check your bobbin tension. There are examples of this on You Tube. Generally if you dangle the bobbin by the thread coming out of it, it should not fall and unwind. But if you gently giggle it up and down, it should fall a bit lower. This is supposed to be your best tension. If it doesn't budge when you giggle, than your tension might be too tight. In this case you will have to losen the small screw on your bobbin case just a smidgen, and try the test again. Don't know if you needed all that information.
By the way, I have been considering ordering the Jenome walking foot myself. I would like to hear from you if you find it considerably better than the Juki foot supplied. I can put up with the noise issue, but not uneven feeding of quilt. How would you compare the feet?
