The errors you have show so far indicative of the library not being installed.
My guess is that the library still isn't correctly installed.
(The SerialLCD HelloWorld sketch builds just fine for me using Arduino 1.0.1)
drewdavis:
6. Then I went to "open program" and navigated into "libraries" went into the "SerialLCD" subfolder and opened up the example "hello world"
Try getting to the example this way:
[File]->Examples->SerialLCD->HelloWorld
If you don't see "SerialLCD" showing up in the list of examples,
the SerialLCD library is not properly installed.
