You'll get better answers than mine but I'll take a shot at a couple of your questions. As for names, this type of plow is frequently referred to as a turning plow, bottom plow or moldboard plow. I don't know which ones is technically proper (if any). The type you have is referred to as a garden plow because of its small size and simple hitch design (for garden tractors).
From what FWJ has said, I imagine getting 5" is about right with a 10" plow.
I think its advantages over a tiller are probably pretty small. It is probably cheaper, lighter and maybe a little faster. Probably does not do as good a job as tilling. I have found, in my very limited experience that my soil needs to be disked after plowing to make a good seed bed. In other words, the plow turns the soil and sod over in long, wide rows. The disk chops and mixes all of this into a more 'loamy' seed bed.
Technically a disk is a harrow but when most people talk about harrowing they mean pulling something over the soil once the seed has been laid down. This covers the seeds and even things out. Harrows come in an endless variety of manufactured and homemade forms (the most common of which is a section of chain link fence dragged behind the tractor.) I have heard of using a disk as this type of harrow and I tried it this year on sunflowers and cow peas and they are coming up great. I set it to the least aggressive gang angles just to get a little coverage. However, the brown top millet mixed in with the sunflowers has not emerged so the disk may have put it too deep. We'll see.
Hope you get more and more technically accurate answers but that's what I know.
There is also an issue of soil compaction which plowing is known to do. Not sure how a tiller compares in this area. Not sure it matters at all in a small garden.
