latter TCA is either in ext_tables.php or in a separate tca.php

if you define at that way, load first the table tt_content with existing 
  values.

t3lib_div::loadTCA("tt_content");
$TCA['tt_content']['columns']['colPos']['config']['items']['4']['0'] =
 > 'SUB-LINKS';
...
this is safe way because you don't delete any values.
If you reset fields, you might take off some field value, which has been 
set by another plugin.
Now you just add or reset defined values.
