It looks like it expects a US format for the phone number... when I entered a 10 digit number, it did accept it.
The grey and white colors are the active and original background colors... this is configurable in the form design, and seems to function as expected.
That is the correct email content as well... the only thing that it seems you are missing is that the email content can be edited directly. There is a page in the webassist/email/templates/ folder that you can edit to replace and customize the email body.
I think most of these issues are as designed, but I'll try calling you tomorrow to look into them and figure out your expectations and how we might be able to adjust the workflow and/or functionality to make it work more like you had expected.
