Nice bike, it looks like you've all bought you need for it's intended use. Bills advice is right for any newbie though you can think about adjusting things for comfort while riding. Little things like seat height stem height the angle of the bars and levers. Things you need to spend money on for upgrades just come to you like a epiphany.
You never know you might end up like me owning 20+ bikes, one for every type of riding imaginable and having to upgrade every component on the frame. Welcome to bicycle madness
