Every LL(1) language is an LR(1) language.  Hard to imagine how Sable
could fail to do it.

Almost certainly, although the language you've got seems syntactically
so simple that using sablecc would be like killing a mosquito with a
machine gun.  Writing a recursive descent parser by hand
seems like the way to go.  Or sre there some tricky items you've left out of
your message?
