The "none" that you're seeing in IE7 is not CSS related or a Gravity Forms issue. It's being written to the page by the script you've included for IE only.
When I removed that, it fixed the issue with the strange text in the select field in IE7 and also the check box formatting on the IE8 form.

It looks like there is still some CSS inheritance problem from your theme in IE7 in regards to the checkboxes and radio buttons. I didn't have much luck tracking that down so far. I would look at your theme for any IE specific styles, and focus on rules for the label and input elements.
The default forms CSS works fine in IE7. You can see an example of a the default styles in the default WordPress "twenty ten" theme below.
