Use a form generation framework, or at least use the same techniques 
that they do...

Hello list,

what is in your opinion the best zopish way to raise input validation 
errors,
dublicate value errors, or other application errors I want to display to the
user?

 Hello list,

 is there a possibility to send the standard_error_message with http
 return code 200 (ok) instead of 500 (internal_server_error)?

Don't raise errors that cause 500 type HTTP error codes on input validation.
It's not an error. It's a user input error.

Hallo list,

because the application error messages like checks of input values 
produce such error messages.
The browser "firefox" does display these messages, but the "Internet 
Explorer" with the newest updates does not.
The "Internet Explorer" displays a own error message instead. Only if 
you manipulate the flag "show friendly http error messages" the
body of standard_error_messages is *always* displayed. But  we think, it 
would be difficult to  make shure that every user does this.

Why would you want to? That's in violation of several http specs...
