Infinity Scroll working with Custom Post Types & on other pages

Hi I have 2 problems.
Firstly I have infinite scroll (IS on Jetpack) working on the posts page here http://goo.gl/HCQwoF but would like to get it working with a new query including several custom post types.

Secondly I would like to get it working on another page other than the default posts page. I have tried several things but can't get this to work.

Any suggestions appreciated.

I have linked the following files on pastebin

home.php - http://pastebin.com/prC6zhJA (this is the working posts page)
front-page.php - http://pastebin.com/SFXTtYUn (this is the not working 'home 'page)
functions.php - http://pastebin.com/PkYCxeFe (the relevant parts of functions.php for IS)
content.php - http://pastebin.com/BUthRiHy (the 'loop' template part of IS)
