... definitely would keep it simple and avoid using RAID by any means at this moments. A single SSD is really fast enough for Photoshop scratch, data volume size you can solve by using 2 or 3TB single harddrives and clone them for system and/or data backups.
My priority list regarding the budget and workload a sense for you from what I heard:
1. RAM, get 16GB
2. Don´t go beyond the QuadCore 3,2Ghz, I would recommend the 2,8Ghz (for Photoshop the additional Mhz won´t cut it)
3. Use an SSD for system/applications and one for scratch - choose the appropriate size (like e.g. 120GB for system/apps and 60GB for scratch) and get the fastest offerings (like Vertex or the new Intel X25)
Think of it: Such a system will keep you smooth enough within Photoshop up to three years the least, definitely, and if your business is thriving, you will be prone for an update, anyway - and can afford the technique at that point of time, which will smoke your soon to be bought Mac Pro no matter what.
Buy what you need for sure, and it will fit your budget. Don´t buy the future, as you don´t know it.
