Tabbed Menu Comment Bubble Aligment

I wondering if anyone has any good tutorials or can help me design a tabbed menu for my webpage https://www.aroaringhome.com

I really like the way this blog has their navigation on the sidebar with tabbed views of each category. https://www.makeitlovely.com

Also, having a tough time getting my comment bubble to automatically align with the post header and can’t seem to change the comment bubble’s link properties without changing the whole pages link properties.

Any help for me out there? I know the tabbed menu will take some extensive work, it’s not the easiest to work with. I just need some help getting started. Thanks!
