Wordpress redesign

I have a wordpress website...

It's a Macedonian content website.

I'm using the theme...

I have made some small changes into the theme but I need much more. I've uploaded 3 images in order for you to understand the instructions better.

Right now on my website (as it is now) the pages that you see at the horizontal bar are, of course, pages. Well, I need them to be made categories. The little image of the green little house will be put first, on the far left side and it will lead to ideja.com (the homepage).

The green link that you see under the search button saying "Предложи содржина", meaning "Suggest an article", I like a contact form to appear after you click on it, like the contact form on the kafepauza.mk website, when you click "Предложи содржина", which is also under their search button.

As you can see on the picture "home", the 9 categories starting with "Мисла на денот" on the far left and finishing with "Тест игра" are representing the 9 main categories of ideja9.com. After you click on each one of them I'd like to see the last 9 posts with thumbnails, appearing exactly in the same way as they are appearing on the homepage. So for example, if you click on the fourth category from left, "Здравје", which means "Health", I like to see the latest 9 posts that have been posted on ideja9.com in the category "Здравје". For the older posts, there will be a pagination at the bottom of course, in order to see the older 9 posts from that cateogry. So that's what will happen after you click on the category.

On the very top of the header and on the footer you can see that three pages are added "За нас", "Маркетинг", and "Контакт". So, I'd like the pages that I add to appear on both those places and the header and footer to look like on the picture "home".

The main 9 thumbnails that appear on the homepage are actually the 9 categories that appear in the horizontal bar, starting with "Мисла на денот" and finishing with "Тест игра". They need to be displayed in the same order as they are in the horizontal bar. The actual thumbnail of each category will be the first image from the last post published within that category. So for example, in the first thumbnail (Мисла на денот), the image that will be shown will be the first image attached in the post for the category "Мисла на денот". In the picture "home", where it says "The title of the post goes here", that is actually the title of the last post published for that category.

That is about the homepage. Now after you open a post, for example you click on one of the thumbnails appearing on the homepage, the design should like like it is on the attached image "individual post". Things are pretty much self-explanatory. The title of the post goes on the marked place and the content comes after it. What needs to be added is the blue link which says "Почетна", which means "Home page". That will take visitors to ideja9.com. And the other link to the right saying "Постари објави", which means "Older posts" will take visitors to the older posts from that category. In other words, if the visitor has clicked on a post from the "Health" category and he clicks on "Постари објави" he will go to the same link as if he has clicked on Health on the horizontal bar.

Any questions, let me know,
