Software Deployment

I have already figured out how to create and unnattend file and deploy silently but i need to also skip the "Default Environment Settings" dialog on first run and set the default programing language to C#.  Also we run our desktops with volitile local users and it would be nice if i could somehow avoid the "Microsoft visual studio is loading user settings" window and have those settings either in public user settings or put into the default user settings.
