Exactly. But for a beginner, it's better to stick to the minor pentatonic at first. Even the minor/major relationship might be confusing at first sight.
Grimmy, just figure out those shapes, ONE AT A TIME PLEASE and play them over blues backing tracks in the key of E. That will be FUN and will help you climb the ladder real fast.
Then read about what I-IV-V means (for instance, E-A-B) and 12 bar blues. Several cool videos about this on youtube. If you want me to, I can do a search and give you some directions. I'll be very happy if I can be of service, really. My email is

Edit: and please don't be afraid of the major pentatonic, the shapes are EXACTLY the same, they just work in a different order.
And if any of the concepts I'm talking about aren't clear, maybe it's because my English is bad and rusty. The other fellows here are free to correct me, you too!
