How to shift the site collection contents & the Quick lunch contents to replace the upper links area

I need to modify my current SharePoint layout as follow:-

1. To display the site collection name inside the upper blue horizontal bar , as shown in the below picture.
2. To remove the free space on the top of the site collection content, and then shift the quick lunch links and the site collection contents to occupy this empty space , as shown in the below picture.

So can anyone advice on how I can do this ?

Thanks
