Of course you won't know for sure without pulling the engine and trans and 
checking it - BUT - it sounds like it could be clutch spin (as you 
indicate) - OR - your throw out bearing could have disintegrated, causing 
the clutch to not fully disengage - OR - part of the disintegrated throw 
out bearing could be caught on the clutch - OR - that missing boot could 
have let a rock get in the bell housing, and caught in the clutch 

With the old throw out bearings (which are carbon faced) it is really not 
good to sit at a light or approach a stop sign with the clutch pedal 
pushed in.  It just accelerates the wear of the carbon face.  With proper 
use, throw out bearings only last about 100,000 miles (which is about the 
life of the clutch, and an engine rebuild too) - a little extra use can go 
a long way to shortening that life.  Last I checked, I couldn't get the 
old carbon faced throw out bearing anymore though - all of them were 
sealding bearing designed.  I liked the old design better, but that's just
