IMO just start with the kit lenses. Yes the quality is not that high but the truth is most people wouldn't be extremely bothered by it. Some of my best photos were taken with my kit lens.
The kit lens offers an affordable, painless way to grow with your camera. Invest in a better lens when you have a better understanding of what suits you. Do you like primes? Telephoto?
Also, the benefits of a better lens will only become truly apparent to you when you are more experienced. Photography is an expensive hobby... when you drop 700-1000+ on a lens you have to be sure you can see why it's worth it.
