CSS Tweaks Needed to WordPress Site

The website it is for is: [login to view URL] What I need done is to make some formatting changes I believe which can all be accomplished by modifying the CSS, but the developer is free to alter whatever parts of the code he/she thinks necessary. All changes needed are on the homepage: [login to view URL] the iframe, the part on the left sidebar directly under "Veterinary Tech School Finder" so that it better fits in the sidebar, and so that the button is the color red and centered in the sidebar. 2. Alter the homepage body so that there are no major vertical white spaces in the list of 10 schools listed in the body. 3. Remove the small blue arrows in the design which are currently there next to all links.
