Software Deployment

We are planning a deployment of Notes 6....

1. Actually we created a MST for the client Notes, one for the administrator and one for Designer. The administrator and Designer are including the client.

Is it possible to install Notes client with the MST and then to only add administrator without the need to uninstal the client and then reinstall administrator+client? We are using AdminStudio SMS Edition and deploying it with batch files.

2. We found Administrator and Designer are not "multi-user" so when a user is starting Notes the admin+designer files are not copy to %userprofile%\local settings\application data\lotus\notes\data. Actually, we are copying the files there manually but I would like to know if its the best solutions and what files do we really need?

3. As by default the files are in %userprofile%\local settings\application data\lotus\notes\data the notes.ini and user.id are there too. What is the best way to secure those files as there are not in a roaming profiles?
