New to piano and Blues. I started playing this past May (I am playing a Yamaha YPG 635) and am still very much a novice at piano.So, please forgive me if I this question sounds sort of obvious to you more knowledgeable types.

A friend plays the harp and got me interested in blues. I now incorporate some blues scales work in my practice sessions. But, I have a question...How do I tie the different scales together so they flow? In other words, if I am running some riffs in the C Blues scale, how do I switch smoothly to say the G or the F etc? Are there some that compliment each other better?
Also still working on getting the right hand to play a riff while the left hand is playing a bass line! I think this is the hardest part of learning to play! My right hand keeps wanting to do what the left is doing!
Anyway, thanks in advance for any tips! I am really ejoyig learning about how the music comes together and actually playing the piano and not having it sound like a skunk in heat! (I actually have o idea what that sounds like!

Cheers
Mike
