Yes, it is certainly worth-while to look for existing org-* functions, I
am still often finding myself re-implementing existing functions.

So your goal is to write a bunch of links into the Org-mode file
following the code block? A couple of suggestions...
- don't call `insert' from your code block, rather output a string and
let Babel handle the insert for you
- it looks like you are doing a good job of using existing link
functions, however in addition to searching for functions with org and
link in their names with C-h f org-link TAB you can try looking for
org variables (thinking existing org regular expressions) with
something like C-h v org-link TAB

I have no idea, I haven't used these functions.

Hope this helps. Best -- Eric
