For a more visual example, this is what your tp2 file would look like.
Edwin's Amulet is misc89.ITM. You could pretty much copy-paste everything here and be 90% of the way there. All that would remain is creating your folder structure and having the .exe in the directory to run, as well as write the name and description you want.

If you only want to change the description of an exsiting item you'd do COPY_EXITING instead of providing a custom itm file.
