Disable some elements

Hi there. This looks absolutely awesome. But I need a simplest solution. So I want to be able to DISABLE some funcionalities. Specially in product creation/edition.
I know you got actions/funcions/filters to:

1.- Can I disable admin access icon at the top/right?
2.- Can I disable virtual/downloadable checkoxes under title?
3.- Can I disable tabs below main product editor area?
4.- Can I disable settings for store manager profile?

I know this can be uncommon questions. But I just want a frontend product manager as simple as possible.

Thanks in advance!!!
