Personally, I would rule out the easier items first.
Have you heard the noise only when moving or also when sitting still?
The following two paragraphs apply if you only hear it when moving:
Check u-joints and centering balls on the driveshaft for play. If you can recreate the noise in normal driving, you can remove one driveshaft at a time and drive around to see if it still happens. If you remove the rear, you'll need to drive around in 4WD (essentially front wheel drive). If it is a driveshaft (or another driveline issue), the grinding will only occur while moving.
Also check the u-joints on the front axle shafts. Checking ball joints and wheel bearings wouldn't be a bad idea either.
If the clutch is original or hasn't been replaced in the past 100,000 miles or so, it may be worth planning on swapping the clutch, throwout bearing, pilot bearing, and pressure plate. Buy the parts and tools now and wait for when you have a few free days to do it.
In terms of parts, you'll want the LuK standard clutch kit (available on RockAuto, Quadratec, Amazon, and others). Most people also upgrade the throwout bearing at the same time.
You'll also need some less common tools, including a transmission jack, external torx driver, and a pilot bearing puller. There are quite a few write ups online on how to do it. This one was very useful:
