One Page Scroll Effect

I’ve used Savia to create a one page site with some inside pages as well. I’ve used anchor tag and linked the menu items to the different sections of the page: http://smartmegh.awesomeliferesources.com/

I face 2 problems:
1) When I place the anchor tag at the beginning of a section (Eg.Services) and the Menu item Services is clicked, some portion of the section gets hidden behind the sticky menu. So, it doesn’t take us to the exact beginning of the section.
2) When the menu item is clicked, it just jumps directly to the place where the anchor tag is placed, instead of gently scrolling to that section.

How do I sort these 2 issues?
