Positioning and wierd problems

Hi again guys, right ive got some wierd issues on the site im designing,

the html is here.... http://www.carl-robinson.co.uk/CHS/Concept2.html
the css is here..... http://www.carl-robinson.co.uk/CHS/main2.css

if you look on the page your'll see the problems,

first the two divs and the bottom i cant get to align properly, i think i managed to bodge it, but then im having problems with the second div's header, the background isn't coming up and if i type more then one word, it starts going down onto a new line.

would be great if someone could help me with this because once thats done i can actually start putting content onto pages to get it finished and up!

also excuse the messy css! and i know theres alot of other things going haywire on there, im just trying to sort this out first

cheers in advance
