Reply to Beginner , need help !

Hello everyone!
I'm very interested with this virtual DJ thing and I have decided to start at summer ( because of holiday = lot of time to practice ).
I need answer to couple of questions:
1. Can I get started with Numark Omni Control ? It would be the best option for me, because of it's low price.

2. I've looked couple threads about your setups and they were all awesome and fancy. Lots of lights and different kinds of gear , but do I need anything besides Omni Control ? Maybe some effects ?

Help me out, I'm new to this whole concept!
