Do the rest of the gears work? Can you take off in first? If your clutch is out, you will likely have trouble getting through ALL of your gears. My tranny is tempermental, when the oil is cold I can't get it into 4th gear.
X2 on checking your linkages, there are measurements for proper runout in one of the TM's. Also check to make sure you have the correct amount of oil in the tranny. I have had my transmission in and out of the truck several times, and there are a lot of other things I would check first before I stripped it down to the clutch again.
Pop off the inspection plate on the bottom of the BH, I was surprised how much I could see through it. If you have a lot of disk material/dust in there, and can't get through any of your gears, be prepared for a full clutch job.
