Few issues with Membership plugin

I am facing following issues with membership plugin.

1. Registration form of buddypress and membership is not integrating. When we use membership registration form then there’s no way to verify email address. If we use buddypress registration page then payment gateway is not showing for paid memberships.

2. If we activate buddypress registration page then it overwrites the membership registration process.

3. Paid membership gateway is not going to paypal and activating VIP membership instantly.
