So basically, you're asking how to round-trip content?

#1) you need to HTML quote your output, or it will, as you've seen, 
break the heck out of the textarea. In DTML you can say <dtml-var 
document_src html_quote> to do this. There are ways of going about it in 
ZPT and Python Scripts too.

#2) when you submit your form, this is taken care of. The HTML escape 
nonsense (&lt; et al.) is a source-only artifact, and what you see in 
the browser is what your code will see after submission. Unless you're 
having problems with this, in which case: creepy.

And your instinct to look to the ZMI is very good: it's a good place for 
examples.
