Changes to Tumblr theme

I have purchased a Tumblr theme and would like to make the following additions to the site seen here: [login to view URL] 1) Change the standard font on the site to [login to view URL] I have already purchased the font at Type kit 2) Change the size of the 6 boxes on the site so that they are rectangles instead of squares and you can see the top if the send row of boxes/posts when you land on the homepage 3) Change the hover overs for so that they only show the first image and do not cycle through all of the next images in a post. Currently when you hover over one of the main words (FOOD, DRINK etc) it flicks through the photos on the post. If you look at an example post you'll get how it works: [login to view URL] Essentially the word FOOD is actually the first image within a photoset post (multiple images in one post). It cycled through the images really quickly which was distracting as there was only ever two images in a post so it just flickered back and forth between the two when you hovered over the word on the home page. 4) Make it so there is not a big gap at the bottom of the page
