Buttons and Sliders

I am revising the website at mattfurness.co.uk and would like to customise the buttons on the home page under the Promotion Headline and Featured Content sections. Probably looking to change the font and font colour, as well as colour on hover. Could you provide the CSS code for these buttons please as I believe they are different, for hover as well. I can then just insert the bits I need changing into Additional CSS. Thank you. In addition, I have just purchased Catch Slider Pro as it includes a few attractive features. Having installed it on the site I am getting the message to update it to the latest version 1.4 when I am already on 1.4?? Secondly how does this work with the Rock Star Pro theme? As you can see I have a slider in place already, and I just assumed that once activated I would get additional features where I add the slider within the theme, but it appears I have to create a separate slider. How do I get this one to show on the site? Do I disable the one within the theme? Many thanks, Chris
