Header Content, Menu, Search, and Side Bar Customization

1. I'm trying to edit my logo and header content text (the site title and tagline) to line up with each other. I want the header text to either be centered or on the same baseline as the logo. How do I do this? 2. I want to edit the border around the search bar so that it's not white so people can actually see it. 3. Is there any way to get rid of that home button? I feel its repetitive since the logo also serves as a home button. 4. Is there anyway to get ride of that gray bar going across the top of the website? 5. Can I edit the width of the posts column and the side bar column that has the recent posts content? Here is a screen shot of my blog: http://www.flickr.com/photos/105697693@N05/11474676953/
