Content alignment

Hi

I have pretty much got everything I need laid out on my site, but now have run into some alignment issues. You will see on all the pages of my site (www.wkrb.co.za), that the content is not aligned in the middle.

Also my featured posts scroll also wont align; I am wanting to make it as wide as possible but when I increase its length the postion doesnt adjust to compensate.

Please advise what I should be doing here.
