You're welcome.
I'm sure all the kit you'll need will be in the box and you'll be enjoying it in no time. Remember to keep the volume lower than normal for the first 24 (ish) hours play so that the speakers can run-in safely. The setup will also sound better the longer you play it.
Later you can look to replacing the free speaker cable in the box with something a bit more substantial - this may improve the sound again.
Don't forget to think about positioning of the speakers too - place them on sturdy stands not too close to walls/corners for them to really shine.
