One big warning about RAID0: if you lose one drive, you lose everything. Two separate volumes is safer, though you do then have to manually manage content space on them.
I totally agree, and I use two volumes on my own Duo for that reason. If you go with two volumes, I suggest going into flexraid with only one disk installed, and then insert the second disk (and create the second volume) after setup. Sometimes the Duo seems determined to use a single volume in flexraid setup, and that can't go wrong if there is only one disk in the system.
Good. There are two quite different Duo platforms - the original Duo (called Duo v1 here) and the Duo v2. The Duo v2 was introduced in November 2011 (replacing the original Duo).
The Duo v1
runs 4.1.x firmware
says ReadyNAS Duo on the front panel
might have v2 labels on the back or side
The Duo v2
runs 5.3.x firmware
says ReadyNAS Duo v2 on the front panel
The Duo v1 is limited to disks of 2 TB or less. The Duo v2 can handle much larger disks. There are posts here from folks who sucessfully installed 6 TB drives. One person did run into trouble with 8 TB (though that might have been due to faulty drives).
Overall, NAS-purposed disks are the best choice for your NAS - Western Digital Red and Seagate Ironwolf will both work well. Enterprise class will of course also work, but your NAS isn't fast enough to take full advantage of them.
The HCL is available btw, but it hasn't been updated in many years - so it is not a useful guide anymore.
It only shows in the wait time, and then only on older RAIDar 4.3.8. But you can destroy the volume it is currently syncing and replace it with a RAID0 volume.

Of course, you really should have a backup; and if you do, it would just be a matter of it taking longer to restore everything.
