(if possible) how can I add a web browser to my vista 3 layout, and (if possible) Use toucOSC as a midi pad

You can use TouchOSC as a midi pad. You will need to configure your app to send midi notes.
You will need to install the TouchOSC bridge on your Vista PC and enable this from the Preferences>midi tab.
