The folder names can be what ever the cheese you wish them to be, their usability doesn't alter... you can even use your native languages names for them, as long as it's using the keys that are compatible with the "UTF-8 without BOM" code in the .tp2 file.
The .ini files are as far and few between as they were before. They don't offer anything new... so it being in a .ini or .tpa for example has no difference.
And to clarify, it's just:
[MyMod-folder]/setup-mymod.tp2
... not any of this mess:
"->[MyMod-folder]
- - >setup-mymod.tp2"
