In add/remove install "NTFS Config" and then launch it "system/Administration/NTFS configuration Tool" Then you will automatically mount your windows drive on boot.
1.) install system-config-samba
2.) configure system-config-samba
sudo apt-get install system-config-samba
click add folder - make it writable and visable and under access make it accessible to all users to let the windows box access this new share folder.
3. under preferences\security change auth mode to "share"
then change the guest account to your ubuntu user name and you are done.
Once you reboot you will have shared folders working and all your drives mounted. This should take care of your troubles
I hope that helps
