Actually Vladimir, Vlad is usually used as short for Vladislav.

I suppose no, '\define...', eh-m, defines a command while '\setup...', eh-m,
sets up its 'style'. When one defines a command one could set its
custom 'style' instead of default.
Consider the following example:
<example file="ex1.tex">
\starttext
\definedescription[definition]
\definition{Hi} This is first definition.
\setupdescriptions[definition][headstyle=italic,color=blue]
\definition{Hi2} This is second definition.
\stoptext
</example>
The first 'definition' would be:
[bold] TEXT
after '\setup...' it would be
[italic] <BLUE COLOR>TEXT</BLUE COLOR>

May be because this is an example? I would say that ConTeX User Manual
shows different commands from context itself and how one could define
custom commands. The '\definition' is one them.

I don't know but reading manuals (context and latex ones), wiki and etc
somehow convince me that 'head' relates with section heading (styling),
for the rest there are '\setup...' commands and 'headstyle' key (not
always, of course), may be that's why I always consult reference on wiki
and sometimes source code.
