WP Customer Area

We are looking to incorporate the following features into our website: 1) Users are able to sign up from a specific page on our website (email will need to be verified). Happy for this to be WP registration bought into a page. 2) Once users sign up, they will be able to access their "user area". Within this, they will be able to customise our item. We simply need six drop down fields with a list of products in them. The list needs to be manageble through the admin by the admin and also the admin needs to be able to see what each user has selected in the area. Users can then also change this any time they wish. 3) We also need to be able to link to other pages of the site once the users have logged in (eg a special contact form we will make using contact form 7). If you are planning on using premade plugins please let me know which these are. We will not attempt to do this ourselves, we just need to know in order to be able to pick the best solution for us. Thanks!
