Slider and Header and Empty area on blogger?

Hi there
showstorem.blogspot.com
please, on the above blog, the slider is on the header, so how can I separate them from each other?

Also there is wide empty area under the header, so how to fill it?

Please help and many thanks in advance

 

Holy moly,

too much code to look at.

I haven't really used blogger before but I'm sure you can control most of the webpage within the portal.
