Table around my wordpress

Hello

Im trying to get a grey backround running down the left and right of my word press I kind of have it at the moment, except certain bits of my blog run out side it, im not sure if maybe I should put my whole wordpress in a table to make it the right shape?

here is my website: https://buggedout.net

Also I cant figure out why my footer is to the left and really high up.

If any one could help
it would be much appreciated

Jack
