Generally, look for AppleScripting examples in the app you wish to 
call. Once you know how it can be scripted, you should be able to 
call TclAppleScript trivially. There may be reasons, depending on the 
nature of communication, why you'll want to go to the additional 
trouble of using my TclAE. One reason is that many apps support 
AppleEvents for which they have not provided an AppleScript 
interface. /If/ you can find documentation of those AppleEvents, then 
TclAE is pretty much your only option for exploiting them.

Because it is never meaningful in a Mac application. A Mac 
application cannot be launched from the command-line because there is 
no command-line so there can't be any command-line arguments. You can 
use MPW or tclsh or Alpha or any number of other tools to emulate a 
command-line on a Mac, but you cannot change the underlying truth 
that the Mac does not have and does not understand this mode of doing 
things.

TclAppleScript is included with the standard Mac Tcl distribution: 
[package require Tclapplescript].

TclAE is presently documented at 
<http://www.his.com/jguyer/Alpha/TclAE%20Help/>. I don't recommend 
you download that library, as it's rather old. I should be uploading 
a current version soon to <http://sourceforge.net/projects/tclae/>. I 
will post here when that happens.

The CW IDE has extensive support for AppleScript and general 
AppleEvents. I don't have my CW docs handy, but if you look through 
the manuals for the IDE, you should find it. Instructing the IDE to 
compile and link is certainly feasible.
