Theme: Portfulium – layout, page type??

Hallo WordPresser,
I just installed the theme Portfolium from wpshower: http://portfolium.wpshower.com/.
I want to built my website like the one on the demo website. The pages and menus I created are page type: blog. I’d like to know where and how I can set up the page type into a normal (static) page, one in the portfolio/album page type with the squares, one blog type page and one menu/page “Social” with “Twitter”,”Facebook”,”Vimeo” links as submenus .
And the menu layout looks weird and not like on the demo. i’ll try to fix it in the css file.
I hope someone can help me.

Thanks a lot for your advices!!!
Best.
Lea
