Help URGENT. Settings are WRONG for PRINT

Hi

I am doing brochure's for my company. I am from South Africa.

I use Illustrator for the brochure, Layout and Text.

Last month the printer had problems with printing the brochure. I discovered my settings are wrong.

This was the settings:

Then I did research On Adobe Community Help and changed it to the below but its wrong too

Can someone help me to set it right according to RSA printers settings, something like a default setting.

Last Month the printer said the below:

- fonts are not embedded.

- black is not on overprint and is 4 colour black

I never had this problem before, so I have no idea what went wrong all of a sudden.

Now when I open my prevoius work on Illustrator or Photoshop, a small window pops up saying work is not according to this settings, etc.

Please help. Im desperate. I need to start my new brochure tomorrow

Thank you in advance
