Congratulations!!
You'll have to:
1. Send different envelopes for each applicant listed in your application, including you.
2. When it comes to documents to send: Print RFV for each, take photos (focus on the specification mentioned) for each, have the asked for eye color and height (add one for each on a white paper if so), all VFS forms for each, passport. That's all you'll need. But do cross check what they asked in the list of documents too.
3. About the photos - make sure to not smile, the photographer shouldn't edit your body, a white background is preferred, and the dimensions should be the one mentioned over email. It is better if a photographer has done it before (gives you a peace of mind)
