I already ordered a set of D'addario Pro Arte strings so those will have to do for now. As for the tailpiece, I had no idea it would effect the sound/playability. is this what we're talking about?:

I have a luthier friend that will be setting up the instrument so I'll bring the tailpiece and strings to him.
