check out clutch rebuild videos under LUNMAD on youtube.

You should have investigated the clutch rather than ramming it into gear but I guess that you know that now. I wish that I understood the stuck clutch thing. It seems far more prevalent in the non UK areas.

OK, I purchased a Clutch hub puller from ebay for $20. In a few days I will try it out and we'll see what happens. In the mean time Should I go ahead and open the gearbox? or is that pointless until I get the clutch hub off?

You cant take the gearbox apart without first removing the clutch.You also need to remove the engine sprocket on the crankshaft with the chain.It might just be possible to get the clutch off if you take out the primary chain tensioner so the chain is slack.But,i doubt you will.Some triple primary chains have a split link but they are sods to reassemble

If you've removed the clutch mainshaft nut and the cush-drive,you could select top gear and start looking in the gearbox.That just means remove the outer and inner covers and "look".Looking doesn't mean touching or removing anything.

You can always remove the clutch hub later.If you need to remove the clutch hub and gearbox mainshaft,you'll have to fit the inner cover back in place.
You won't need to index the camplate at that stage,but it's simple enough to do that too.If you mark the quadrant position before you remove the inner cover,it's easier than me explaining how to do it from scratch.
