I’d really begin to dig into their support forums and Google. Ask things very specific and chances are someone has had the issue. For the slider revolution, you caa insert it as an element within Cornerstone to any band, column etc. Make sure you set what ever container its in (Row and Column and Section) to have 0 padding if you want it to fill the screen.

I don’t use Contact Form 7 – I use Jotform for all of my forms. I find it to be the best service out there for email forms.
