Make Homepage show only Slider

Hello,

First of all, thanks for creating Hueman – it really is an asset for any WordPress website.
My problem is, when I first installed the theme, there was only the Slider on my main page – which was awesome. Now, I see that my oldest posts are getting accumulated below the slider. (P.S: I have unchecked “featured posts in content area” and I have also disabled “related posts.”) Is there any way to make only the Slider appear on homepage? Also, is it possible to auto-animate the slider?

My other question is: is it possible to permanently disable the default thumbnail feature? – because my posts have no thumbnails attached to them.
Also, how can I modify the size of the sidebars (apart from the options given in “Theme Options”)
Finally, on the Second sidebar, how do I change the title from “MORE” to something else?

Thank you in advance for helping me out with these queries. Once these are resolved, I shall be able to properly launch my website (which gives out Free Medical notes and lectures to Medical students).
The URL of the site is: usmle.biochemistryformedics.com

Thank you,
Sincerely,
Dr. K.
