No and Yes..
Officially TRIM is not supported in RAID, but the latest Intel RST driver is reported to support TRIM in RAID. But I have not seen where they have officially stated it is supported yet.
And with F/W Version 5.02 TRIM may still work it is just that it was identified in some configurations TRIM May not work.

However in any RAID configuration I would suggest using Diskeeper Professional with Hyper-fast technology to maintain drive performance If this is a problem.

And to update the Firmware you will have to break the RAID and run the drives in AHCI Mode then update the firmware. I would strongly suggest backing up the array just to be safe but the firmware update is not destructive so in most cases I would not expect to loose the data.
