The "kit" lens is perfectly acceptable for most people. It's not as if you will immediately notice the difference between pictures taken with a $100 lens versus a $2500 lens.
The cheaper kit lenses are made to be decent all around, so they are perfectly acceptable for a beginner.
Future lenses are need specific. Want to take very low light pictures, get a prime. Sweeping landscapes, a wide angle. Close ups of flowers, time for a macro lens. Distant nature shots, birding, etc, time for a telephoto. Indoor sports.. Then you may want a telephoto with fixed aperture.
You usually don't save a ton of money by buying "body only"-- and the kit lens is usually well worth the $100-$200 price.
To cheaply start improving your photography... A nifty fifty lens is usually helpful. 50mm/f1.8. Usually sharper than the kits, great for portraits, great for low light. But won't replace the kit lens in all situations.
