membership and bp, registration process and registration forms

I am setting up the following:

BP site with membership plugin.

On membership plugin i have setup

4 levels = 1 free and 3 paid and 3 subscription levels.

1- Show levels on a registration page or packages page as a drop down option and buttons with some text about the level.

2- Create custom registration process

3- Do not send confirmation email and notify specific users to take approval steps for the new user/account.
