LinuxQuestions.org - Linux and Windows connectivity for backups

I currently have Linux Slackware 13 (64 bit) installed that right now is not working all that good because of a hardware failure that has been sent out for repair (piece broke off the motherboard) so I am using a computer that is no where near the specs that it is normally (slower processor and 1GB of ram instead of 4GB). When I get the parts back (should be Friday) I plan on redoing the system, what I want to do at that time is have it set up and have samba working for file sharing (works now so I don't see why it wouldn't after a reinstall) and have some sort of script running on the windows machines (Windows Vista Home, Windows7 Ultimate) maybe like a *.bat file to back up certain directories on the Windows systems compress the backup and send them to the users /home directory on Linux or a backup directory that I can set up lets say on a weekly or bi-weekly basis. Right now the Linux system has 2 320GB SATA hard drives in it and there is plans of getting a 1TB or greater drive in the near future. As you can see below space and usage is not a problem.

/dev/sda2, /dev/sda3 and /dev/sda5 are swap disks. When I reinstall I think the only change I will make is instead of having /home on its own partition is let the system put it in the / and then when I do get the other disk I can make 2 or 3 partitions on the new drive and have one of them for /home. Is what I want to do possible or is there a better way. The other thing I want to do is set it up so that all the windows machines (6 of them) when they download it goes to a partition on Linux, I want the users to be able to download the files to Linux copy them to there own windows computer but I don't want them to be able to delete the files I want this to be done by the administrator. Is this possible, if it is I think it would be a directory permission or a smb.conf setting for the download share and I am horrible at permissions so I wouldn't even begin to guess on how to do this. Thank you in advance for any help you could spread on this subject.
