Why keep the superdrive? Apple Superdrive is the pinnacle of stupidity throughout the era of personal computing.
You'd be better of replacing the HDD with a Hitachi 4TB and putting the SSD on the superdrive's slot with an adapter from MCEtech.com instead.
The superdrive (if you insist on having it anyway) can be put into a USB 2.0 enclosure and be stashed somewhere until you need it.
The best way is to partition the SSD into 3:
1) Mac OSX
2) HFS+ partition for Adobe's scratch & caches folder and/or for stuff you're using.
3) Windows 7 64 bit
And it is best to partition the 4TB HDD:
1) Scratch folder for your footages, libraries, render files, & etc
2) Archive of your older projects & Windows 7 Backup Image
3) Bootable Mac OSX Back Up partition
Or you can just wipe Mac OSX, install Windows 7 64bit, and just play crisis with the iMac
