User Management in WordPress

Hello Everyone,

I love wordpress no doubt but i think its user management feature is not flexible enough for all developers. I am very new to wordpress so there may be cause the my requirement below is already delivered out of box, but if not, could you please suggest me some plugin or any other setup to achieve this.

1. I want user to be able to register/login/update their profile from front end.
2. I do not want to give them backend access (except Admin)
3. Registered/guest user should be able to publish their post from front end
4. When user is registered the email should not be triggered from [email protected]. I should be able to select email of my choice.
5. User should be able to select his password while signing up, he just need to validate his registration.
6. When user is loging in he should not be directed to backend. He should go to frontend.
7. Toolbar should be disabled for all user except admin.

If these all can be done by a single plugin that will be great as i want to minimize the number of plugins in my site.

Thanks,
Avinash
