Hi Josh Thiessen,
For question 1: Even you share the IE program, I’m afraid you still need to maximize the IE window in order your attendees can view full web page on their meeting console.
For question 2: The gray box that appears when the Presenter accesses the Live Meeting panel is by design. This is because the presenter is sharing an application and anything that is shown on the screen that is not that particular application will appear as a gray box to all of the Attendees.
For question 3: You can partly customize the meeting console in LiveMeeting conferencing administration web console by clicking “Administer”à “Account”à”Customization”à “Branding”à “Create new branding”à “Step 6-LiveMeeting client Image”. However you can only change the image on meeting pane in LiveMeeting Client.
Hope this helps.
