I second the guy that said "go out and play, let the experience dictate what you need to buy..."
100% agree with this. Most people will buy a rig then blow $$$ on gear they never end up using. This is not the way people should go about anything in life. It is all about starting simple and pushing that to the limits in every area of life then finding out what would benefit and strengthen to allow for greater capabilities.
I would rather trust a guy with experience and a bone stock rig compared to the one without experience and a built rig. As time goes by you will find out what you will need.
