Hey there!
There are a couple threads about the technical parts - how to mount an adapter, how to meter with an A lens, etc. So search for those if you need that kind of info.
What I would say is to simple put the aperture ring to A position (you probably have to push a little button on the aperture ring for it to lock into A). Now you have aperture control on your camera and you can use Av mode normally
For something similar to AF you can look at Catch in focus (CiF, focus trapping). Its not true AF, but its close. The distance scales on that lens can also be helpful, especially if you are doing zone focusing (or hyperfocal focusing). Just keep in mind the distance scales are from the sensor to the subject, not the front of the lens to the subject. And the DoF scales are made for full frame film cameras, not for modern day digital sensors with high pixel density - this means if you are using f8, you should do zone focusing as if you selected f5.6.
Edit: Ugh, my post is a jumble of information.. hope its more helpful than confusing
