I took a sampler class and they used the "Quilts, Quilts, Quilts" book. I found it to be a very useful book.
One of my favorite patterns to date is the 4-patch. It is a beginner's dream because you can learn so much of the basics (cutting acurately, pressing in opposite direction to nest the seams, etc.) Plus, there are a gazillion (or more) options for alternating squares.
Just have fun and don't stress. Which machine are you getting?
