Update a site in Wordpress 3.5.2

I need to make some change in thin website in wordpress 3.5.2 [login to view URL] 1. the new cakes that I am adding to be show on top of the page 2. to add a new category in the cake category: CAKE FRUITS 3. to be able to add more than 1 picture at the description of the cake 4. when you open a category, because they are a lot of cakes, I want to be able to see the cakes in 2 columns, and maybe to have a limit per page , so the page not to be so long. Right now, for example, if I am opening [login to view URL] i have to scroll down a lot to see all the cakes. Put the cakes in 2 columns and also put numbers to the pages, so if they are more then 12 cakes on a page,to move to the next one. 5. add LIKE button for FACEBOOK, twiter and pinterest Thank you!
