As far as I know, the port just outputs whatever is displayed on the screen without any software interaction.

Many ROM routines use TI's error handler which (as far as I know) no one has found out exactly how it works. (Maybe Dines?)
Anyone who has some additions to those files could make his own text file and upload to ticalc.org!

Dunno.

Iterate through the program/list VAT and make a nice menu like Ash/CrAsh... Can't be too hard!

Check out the Little Dude 2 trainer (with source) by me :-)
It uses interrupts, so the method does not work with Penguins... although that maybe could be arranged :-)
