Hi, Ahmet,
I, too, am currently using version 1.8.4, so that's good.
For the primary school course, I am using Michael Penney's Flexpage course format --
http://www.moodlerooms.com/intel.html. That makes it very easy to put in the tabs or not, get rid of menus or not, and so on. It takes a little getting used to, but it is great for this sort of thing!
For the "Listen " bit on each page, I just record the text on the page and save it as an MP3. Then I
upload it to Moodle. When I link to that file, Moodle creates a Flash player for it. I just have to add the ear.

I hope that is a little helpful. (The primary school teachers here have been quite positive about it.)
Best regards,
Art
