, just in case something goes wrong, so you could at least get the device back to stock. There are 2 ROMs available, I do not know which one you would need, so be careful.
After reading the comments at NeedRom, without factory firmware or recovery available/created for this specific device, I don't think the "safest way" requirement can be satisfied. I suppose it depends on the level of risk you are willing to take.
Personally, I would wait for it to appear on NeedRom (assuming you have the 3GB version) as working, get it from the vendor, or create my own... unless the device is basically a disposable testbed or toy.
