Any one have any advice how the order to replace the 2 drives that failed or if that even matters?

I should mention the RAID card is PERC 6i and there are 8 physical drives. I'm inclined to replace physical disk 6 (failed 2nd) first, hope that it rebuilds. If that is successful, replace physical disk 3 (failed 1st). This way is logical IF physical drive 3 was the hot spare, the array would remain up and then after the 1st drive 3 failure, physical drive 6 of the same RAID 5 array fails, now the array is NOT fault tolerant. So, it sounds logical to replace physical drive 6 first (and hope for a rebuild that doesn't kill another drive) then when the other replacement drive arrives, replace physical disk 3. Any RAID guru out there that can confirm the best order in which to replace the drives so as not to lose data?

EDIT:

So, physical drive 3 is in the READY state but failure has been predicted; physical drive 6 is in the FAILED state. Also, this RAID was NOT configured for a hot spare so i am majorly running on borrowed array-time!!

Here's exactly how i remember finding the drives: one day i see a drive blinking amber. I usually remove the faulty drive and leave it out for a little while. Then install the drive and see if the drive goes back to green or continue to blink amber and it when green but only for a little while. I left the failed drive in the array and ordered a new drive. Some days later, i see a different drive in the same array (RAID 5) blinking amber!! I also noticed the other drive that failed is now blinking green and amber. I login to OMSA and the physical server, data in that array that has 2 drives fail, is accessible. Now, i have 1 replacement drive and waiting on another replacement drive. What failed drive should i replace first in hopes to save the array?

No one can offer any insight in this matter?
