I am not a designer by profession and don't really want to become one [not my cup of tea, I guess]. I want to gain some knowledge on graphics designing [mostly with XAML] so that I can at least work with Expression Design and Blend. Any book or video that can teach me some effects would be good.
What are you favorite resources to learn Expression Design and Expression Blend? How can you learn to create effects like, shine on the button, etc?
Have a look at these courses and tutorials. .Toolbox They'll walk you thru various design scenarios and principles.
Just don't be afraid to try things out. Add lots of different layers on top of eachother with different gradients, a small line or curve here and there.
