Before you start moving files around get Samba configured and running properly first. If using webmin then you set up your users through there - in a simple setup each user gets their own data area and the permissions on that area will be that they alone can read/write to that area. Normally in a business setup you would want a "shared" data area also and the read/write permissions on that will be group based. Read up on samba.conf.
Much will depend on whether your Lnux box is going to be a primary domain controller or you are happy with simple workgroup sharing. Former is better from a security point of view but latter is easy to implement.
Once you have got samba working as you want then you can move the files via windows which will put the correct permissions on them. If the NTFS disk is in the same physical location this is going to be a 2 stage process i.e. move to PC then move to Samba. Perhaps consider removing the HD and temporarily putting it in a windows box as a slave - or did you install Linux on that disk as a dual boot.
