HP StorageWorks MSA60 Installation

Hi Experts, I will be purchasing a storage array in the next week or so and have been reading through EE for the past three days now on the subject.  My head is spinning, so let me just lay out what I want to do, what I think I need to buy, and you can tell me if I am on the right track or not.  

I have two servers, they are both HP DL360 G4's with 2 Xeon 3.0ghz processors.  
 - Server 1 is running Windows 2003 Server Enterprise and is a database driven application server
 - Server 2 is running Windows 2003 Server Standard and is our Exchange server

I have completely run out of room on my exchange server and the app server is getting a little cramped.  Instead of buying and setting up two new servers, I was hoping to setup an MSA and move the databases to that.  So here is what I think I want to do:

- 1 HP StorageWorks MSA60 (HP P/N 418408-B21) with...
     4 72 GB SAS drives setup in RAID 1 + 0 for my App Server (375870-B21)
     3 36 GB SAS drives setup in RAID 5 w/ 1 Hot Spare (total of 4 36's) (375868-B21)
     That will leave me with 4 open bays for future use
-2 HP Smart Array P600 Controllers (337972-B21), one for each server, with SCSI (SAS) external cables

So basically what I want to do is setup two seperate and independent LUNs within the one MSA60, one to be accessed from the App Server and the other from the Exchange Server.  Can I do what I want with this shopping list?  Do I need any additional controllers, I/O ports, etc.?  I haven't been able to find much information on actually physically setting this up the way I want, so I do not know if I am missing anything or not.

Thanks for your help.
