Container transparent / Homepage

Hi there,

I have two questions I am dying to learn:
1. how can i make the container transparent, so that all the content (text,pics etc) lying just blank on the main background i stetted up?
2. how is it possible to set up the first page / homepage with a static page i created (like:about) but I still wanna be able to use the 'latest work' widget plus 'hello text', though I'd prefer to make those sections below my own content?

Any help is appreciated.
Thanks in advance.
