Start low, and adjust UP. Otherwise you are in danger of moving the lens DOWN into the slide, breaking the slide, and maybe damaging the lens. Do not ask me how I learned this- OK?
I believe it's the coarse adjustment.
Yes, but only to do the most basic focusing. Keep in mind that you can break your slide if you move too close with the coarse adjustment knob and any focusing close to the slide should be done with the fine adjustment knobs. (taught HS Chemistry). Hope that helps!

The coarse adjustment knob elevates the microscope's stage up and down quickly. The fine adjustment knob does the same thing but more slowly and accurately. In other words, the fine adjustment knob should require more revolutions to elevate the stage as much as the coarse adj. knob does.
high-power lens
The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.

You should not use the coarse adjustment knob when you can see a blurred silhouette of your object. Then you use the Fine adjustment knob to zoom in on it for a sharper image.
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
