1.7.10, custom pack

Ok, firstly in the cofh core config it has an option to replace vanilla ore gen. IF I leave this false end edit the json or make a new one, will it keep the vanilla ore gen and just add new ore gen ? Or does it need to be set to true to actually generate anything ?

Second, GregTech ore gen, how does it work ? Does it automatically disable vanilla ore gen ? What about other mods ?

Thirdly, does GT oregen override whatever COFH worldgen I set up ?

And last but not least, easiest/best way to add new worldgen in an existing world ??

Thank you for any help/comments !
