Problem:

Q1) Design the page with Bootstrap version 2

Q2) Move the Jetpack-feature "similar posts" in Layouts cell

Solution:

Q1) You are using CSS class "span9", "span7", which is a Bootstrap version 2 CSS class:

http://getbootstrap.com/2.3.2/scaffolding.html#gridSystem

Please try this:

You can use other plugin to load the version 2 of Bootstrap CSS, for example:

https://wordpress.org/plugins/wordpress-bootstrap-css/

Activate it, then go to:

Dashboard-> Twitter Bootstrap-> Bootstrap CSS

option "Bootstrap Option", choose "Twitter Bootstrap CSS v2.3.2", and test again

Q2)

1) You can disable the "related posts" section

https://jetpack.com/support/related-posts/

2) You can use the [jetpack-related-posts] shortcode to insert the Related Posts in a custom location within your post content. Once you insert the shortcode, Related Posts won’t appear at the bottom of your posts.

https://jetpack.com/support/related-posts/customize-related-posts/#shortcode

They are all in Jetpack plugin side, you just need to put the jetpack shortcode in layout cell.
