How to remove author and change font of post title

After one day of working as an extreme novice I've got my site looking pretty darn good. I just can't seem to figure out how to remove the author name from the post title and how to adjust the font size, color etc. I'd also like an italic font for the post title with a different color for the date and title. It seems that the CSS changes I made to the whole post has changed the title as well. http://interiorsalvagedesign.com/ How can I fix my squished title? Any help would be most appreciated!
