More RAM would be helpful. It's not that expensive, compared to the rest
of your system.

If you have a good RAID controller with BBU cache, then there's no point
splitting the discs into two sets. You're only creating an opportunity to
under-utilise the system. I'd get ten identical discs and put them in a
single array, probably RAID 10.
Also, do you really need 6*750GB for OS and transaction logs? How big can
they be?
However, the most important factor is that you get a good BBU cache.
