If you want to just learn a tool (especially just at the pragmatic
level), learn ANTLR first. If you then want to master a tool and you
have serious parsing ambitions (i.e. you want to understand the
theory), you want to master LR parsing ala yacc/bison. If your issues
are totally pragmatic, mastering antlr is sufficient.

Learing antlr (recursive descent parsing) is considerably easier.
Learn it first.

As much as any book can cover transforming grammars from LL to LR (and
that isn't really a covered topic in any textbook I've seen, mostly
because most LL grammars are already LR), the original "green dragon"
book is still just fine.


Just some opinions,
