On the lighting subject, I have two daylight strip lights in my room, and they do make a world of difference. If you change your lighting, do your research first. Daylight strip bulbs come in various 'lumens' and also various 'warmths'. For what we do you want one with a high lumens, but at the cool end of the scale. 'warm' lights alter your colours, which is why normal bulbs distort colour, most general light bulbs have a warm light, for obvious reasons.
gives a good explanation, and recommendations.
Storage wise, Expedit Cubes, every time. Best storage I ever bought. The internal dimension of each cube is 13" square, so holds pretty much anything. Plus you can have them open, or add doors/draws/boxes to them. They come in an assortment of sizes and colours too. I have a 5x5 and a 4x2. The 4x2 has an (optional) desk attachment you can buy, which I had and has my Big Shot Pro, cuttlebug etc on. The cubes hold all my plates, dies etc.
