"SP" is just TAMRON's designation for "High Performance Specifications"
"AF" is, indeeed, autofocus
"Di" = Full Frame Digital qualified
"Di-II" = APS-C Digital specific
"XR" = Extra Refractive Index Glass
"IF" = Internal Focusing
"LD" = Low Dispersion glass element
That should cover the basic label designations.
