Do I need to worry about over running buffers when calling serial.write()? Or will it block 'till it has room for the data I called it with? I can't find any info on how this works.
Thanks!

I can't find any info on how this works.
Why not? You have the source code. Look at it.
If there is no room in the buffer, the function blocks until there is room. On 1.0, the buffer size is 64 bytes. On 0023 and earlier, the buffer size was a bit smaller - 1 byte.
I have the source code? Really? Where?

On my Windows PC, version 0022:
C:\Documents and Settings\Owner\Desktop\arduino-0022\hardware\arduino\cores\arduino\HardwareSerial.h
C:\Documents and Settings\Owner\Desktop\arduino-0022\hardware\arduino\cores\arduino\HardwareSerial.cpp
Depends somewhat on where you installed it. So basically:
<install directory>\arduino\hardware\arduino\cores\arduino\HardwareSerial.h
<install directory>\arduino\hardware\arduino\cores\arduino\HardwareSerial.cpp
Oh cool! Thanks!

On my Mac, version 1.0 it is:
/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/HardwareSerial.h
/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/HardwareSerial.cpp
Found it and it blocks. Was even a note about what it should be doing.
Thanks again, this will be a great help.
