Linda,
you should still be able to get some good sharp photos with the kit lenses. You just have to find their limitations and where they perform their best.
Take the first one, it is nice in sharp in the area that you were focussing on. You just need to change your aperture. You were using f5.6. That lens is better at about f8. That would also have given you a bit more depth of field. By changing your aperture, that would have slowed your shutter and that has the potential of introducing camera shake, ie soft photo. To compensate for the slower shutter speed, you can increase ISO or use a tripod.
For the second one, your shutter speed, 1/125s was too slow for the focal length 220mm you were shooting at.
Just keep experimenting until you know the limits of your gear, once you know that, you will see your photos improving.
Cheers,
André
