In other words, is this critical to drain this along with the dry-sump tank and engine, since it amounts to so little oil in the big-picture?
No. You do not usually drain the turbo drain tank. Actually, if you hold the throttle around 2000 rpm for 15-20 seconds before you turn off the engine, the turbo drain pump (attached to the back of the left bank camshaft) should mostly drain the turbo drain tank for you and pump it into the large oil tank beside the rear passenger wheel mentioned by Rarlyl8. This usually eliminates the characteristic puff of blue smoke on start up (if you hold your mouth just right).
