I got into Scheme by reading /Scheme in Fixnum Days/ together with the 
R^5RS standard. The first one lacked some introduction to the language 
constructs but provided some really good examples. Then came the 
/MzScheme: Language Manual/ (it mentions only the differences from R^5RS 
so it's not sufficient alone) and tons of really cool articles from the 
PLT guys behind Mz. (especially the macro ones)

/Programming Languages: Application and Interpretation/ by Shriram also 
looks really nice to me. I have only read the macros part but it blown 
my mind. :P

Of course writing some useful software is also quite enlightening. I 
started (however that probably wasn't the wisest choice) by wrapping 
libusb with the FFI and writing an AVR programmer.
