First install M2DC. With this app you can change the default browser. After that install "I C Thru U". This one let's you make "transparent" the operator, taskbar, bottom bar, etc. at your choice.
All these apps can be found here in XDA and I know there are some more but I don't remember.
Always make a backup before doing any change to your device (I use SPB Backup).
Hope this help
EDIT: Forgot! With shortcut manager you can edit (i.e change the icon) any shorcut in your device and make new ones.
