How To Track Account Details

We would like to track various information about each account directly in MSP. I have a few questions:

1) I know we can add additional fields in the Account section. Problem is that only a system admin can make these changes. Is there any way to allow technicians to update this information?
2) How can I run a report on the details in the account tab?
3) Is there a better way to store this detail per account?
4) Also saw in the latest release notes there was some changes made in Accounts. Can you please explain what this is:
