Additionally,the original Smalltalk "Blue Book" ("Smalltalk-80: The Language and its Implementation") is well written and can be a good introduction.

If I wanted to try out examples in the book, can I try in the Pharo environment?

Pharo has some new syntactic additions. Cuis smalltalk is closer to Smalltalk-80, if that's what you're looking for.
