Hi there! Lighting is definitely more important than your camera. If you can't photograph outside or it's not sunny, you need a daylight light source - I have a Lowel Light that is a daylight fluorescent bulb - two actually - covered by a diffuser. For me it's more of a space saver and easier than the light boxes. I don't have a lot of room. But you need diffuse high kelvin (color temperature) light directed at the front of your card. When looking at fluorescent lights, they need both a high color temperature - 5500 is good - and a high CRI - this is extremely important. CRI is the color rendering index, and you need to get as close to 100 as possible - Lowel lamps are 93 CRI. That gives you the purest representation of your colors. And finally, photoshop covers a multitude of sins. I'd invest in those things if your camera is a 3 megapixel or better before I'd buy a new camera.
