On the Show Your Giant Faith thread, there are tons of photos of great ideas for routing cables. I recommend looking at that thread.
As for the dropout, I felt my bike came alive after I put the lower/longer dropout on. That will be a personal prefference, though. There's no way too know which you'll like more until you try both.
Just remember (though you probably already know)- Lower/Longer for fast and steep; taller/shorter for more tech and less steep. If you'll be climbing often with your Faith, I recommend the taller/shorter one.
ohh! thank you dude i puut the lower and longer option and it feel like a beast with out chains! and about the cables i look and put both cables in one ruter thank you again
