wordpress theme tweak

My Website is [login to view URL] and it's going to be a site about healthy recipes, and will soon add a store to it. I need the following tweaks to the template i downloaded: 1. i need the theme's width to be increased. the content width needs to be about 200 pixels wider, while the left hand side column needs to be 100 pixels wider. i need enough space to accommodate google ads 2. for the main page, not the posts page, but the main page, i need the following installed: [login to view URL] 3. i need the main page edited so that right below the sliding post it will present the most recent posts for two categories (picked at random) ... so it will look something like this --------------------------------------------------------- | | links | sliding post plugin | | | | category 1 category 2 | | latest post latest post | --------------------------------------------------------- 4. of course the post page needs to be made wider ... just like in step 1.
