You can use different heights with different tools, Myself when spindle turning I put the steady rest a little below center, (1/16" to 1/4"depending) [I will caution you not to be confused by the variation in the information below, you will have to find a middle ground and find what works for you] I will provide you with a excerpt and sites to help explain futher:
The key to the roundnose scraper is to lower the tool rest and lock it in place so the cutting edge of the scraper is precisely at centerline. The roundnose scraper is like a steel cliff. The overhanging cutting edge is always on top. I like to use this scraper to cut uniform coves.
By the way, the roughing gouge is only used for spindle turning. It is too grabby for bowl or faceplate work.
So what are these five wonder tools? If you become handy with these chisels, you'll be a master in no time. They are (from left to right above) the 3/16" diamond parting tool (the cross section of the blade is diamond shaped), the 1-1/4" roughing gouge, the 1/2" bowl gouge (perhaps the most important), the 1" oval skew (its edges are rounded for easier use), and the 1/2" roundnose scraper.

Horizontally the tool rest should be set about 1/8" from the farthest projecting corner of the wood and should be readjusted occasionally as
the stock diminishes in size. The vertical height varies slightly according to the height of the operator. It is even with the center of
the spindle for a short person; 1/8" above for a medium person; and 1/4" above for a tall person. So long as the stock is in its square form the
tool rest should never be adjusted while the machine is in motion as there is danger of the rest catching the corners and throwing the stock
from the machine. Also see that everything is clamped tight before starting the lathe.

The backing plate on a lathe is used to mount the chuck to it and is the adapter to the lathe spindle.
A lathe that measures 6 inches from the center of the spindle to the closest part of the bed is considered a lathe with a 12 inch swing.

No, thank you.
A blanchard lathe is a lathe for turning irregular forms after a given pattern, such as lasts, gunstocks, etc.

Using a drive plate on a lathe requires removing the chuck and the drive plate is attached in its place onto the spindle.
There is no difference between a turning machine and a lathe. They are two names for the same kind of machine

One can purchase a wood turning lathe at several locations. One can buy a lathe at a large store, like Sears, or a woodwork store or at an auction site like eBay.
The lathe (apparatus for turning wood or metal) is called "un tour" (masc.) in French.
