Managing Users in WordPress, need help…

Heya,
So I deploy WordPress on every new website I work on. I’m searching for a plugin that assists me with the following:

1. Allows me to create custom user roles.
2. Allows me to hide the items that appear in the left navigation of the admin area for that role.
3. Allows me to hide any panels, such as “Custom Fields” or choose to have them collapsed by default.

I’ve seen plugins that do some of these things, but none that do all of them. Does anyone have any suggestions?

Thanks!
