Gallery + Menu

Hi, I really like the Catch Everest theme in comparison to others but I am having trouble with some issues: - The Menu bar is not working; it only shows one menu button - the rest slide down and does not work - How do I increase the width of the pages where my galleries are set up (i.e. http://bmdesignerfashion.com/mens-collection-2/kurta/). For each gallery page when I hover over the picture the text is quite large - how do I change that text and make it smaller? - When I click on in image (see above)- the gallery format is not very pleasing- How do I make it more appealing? i.e. making the picture larger and blacking out the rest of the page... - How do I make the posts on the slider take me to a specific page vs. a post (I would like to direct my slider to pages not posts) How can I do that? I greatly appreciate all the help! Thank you www.bmdesignerfashion.com
