I was thinking about buying Color Theory.. but I had some concerns. Is there a Nav Bar you can use? I see the one on top but not those ones, a thinner one tha usually goes somewhere. And if not, can you add more buttons to the current one?

Also, I've seen ripped versions, what's the difference? Are they better? Are they illegal?

you can add more buttons to the navbar by just editing it.You can add another navbar one also ... Ripped ones are illegal.
