Footer customization

Hi Sakin, I want to make some changes to my footer but a bit unsure how too. www.soton-fifc.co.uk 1) I want 4 sections in the footer-sidebar, is this possible? 2) Footer-sidebar, I want all the writing in a certain colour, but I am unsure how to reference this in the CSS (I have tried a few things). 3) I want a title for the twitter feed in the footer. 4) I want to edit the font and size of the writing of the menu links in the footer 5) I want to add a line under each title (just a little preference). I look forward to hearing from you!
