The best way to partition the two? Don't. Single partition across both of them. But if you really want to for whatever reason follow the directions on http://windows.microsoft.com/en-us/wind ... =windows-7
. The problem with partitioning is juggling partition space down the road. For instance you may think "I want to allocate 500GB to my music and movies" because you're about 200GB or so in. A few years later after compulsive hoarding, you're running out of space on that partition, even though you still have plenty of free space elsewhere. Then it becomes a problem trying to resize partitions and whatnot.
As for imaging software, use Control Panel\All Control Panel Items\Backup and Restore and in the left pane select "Create System Image". You can do this regularly, but I usually just create one after I've installed Windows, drivers, and the base programs I know I want to use. If you want to use this, it's just a matter of going into the recovery mode and selecting the option to recover from an image.
