Actually...I think that you currently have things set up quite well.
There is no reason to have more than 40GB set up as the system/Windows/C: partition. That size is probably as large as I would suggest for a system partition and I don't believe that having only 1 hard drive is superior to having a smaller drive for Windows and a larger drive for data storage, backups, etc.
If you insist on using the 1TB drive as the sole drive...bear in mind that placing all of your eggs in one basket could be regretted later.
If the Windows drive develops problems...you still would have access to all of your data files with no fear.
If the data file develops problems...you would be able to troubleshoot it much more effectively from a working Windows install.
Ultimately, if you want only one hard drive...you could always use cloning software...to copy a duplicate of your 40GB drive to the big drive.
