content profile

First I tried this with taxonomy, and now I'tried to solve my problem with te Content Profile module.
I'm wondering if it is the right choice, because I can't get it to work.

This is what I want:
Users can go to my website and download documents , these documents are related to projects.
I want the users to see only the documents of the project that they are related to.

To achieve this, I installed Modules CCK and Content_Profile.
Then I set this up:
- projectdocuments have a node reference field to project
- user_profiles have a node reference field to project

Hello!

I would like to create a webpage for my brass band. In this webpage I would like to store information about the members of the brass band, e.g. Email, telephone no., birthday, instrument etc.
The users of the site should have the possibility to maintain their own data. But I have now the problem that not all members of the brass band have internet access and/or email addresses. Therefore I can't create for each member of the brass band a drupal user. As I said, for those who have access to the internet, it should be possible to maintain the data by their own, for the others I (as admin) am willing to maintain the data.
In the site I would like to create dynamic lists like a telephone list, birthday list etc. over ALL members of the brass band (e.g. with views).

How can I solve my requirement within drupal? As far I understood, it is madatory to have an email address for drupal website users ...
