Install small calendar, make backgroung image continue forever & put dots in between menu items without it on mobile version

I have four small tasks I need completed for under $50. 1. I have a calendar I would like installed, [login to view URL] I am open to a different but similar looking calendar if it has an ADMIN interface as this one does not? 2. My background does not go forever, I would like to make it infinite. 3. I would like simple • <- dots between the menu items, WITHOUT it appearing on the mobile menu as it looks stupid on the mobile menu when they are placed in the HTML 4. The toughest part, I have an existing BLOG script, it is a simple PHP blog, I would like to have it coded so that the BLOG POSTS can have META keywords to help each post attract viewers.
