i'm no digital painting wiz (i share you want for an easier/quicker way to paint), but i found digital painting got a lot easier/enjoyable when i installed these brushes. in particular, one brush called "painterly" in the set. i looked at the settings of how this brush was made and noticed a few in particular that made all the difference (this is on ps cs2):
- brush tip shape > spacing: 2% - by keeping the spacing down, the brush strokes become smoother and more solid, especially at a large scale.
- shape dynamics > size jitter: 0%, control: pen pressure - control the size by pen pressure.
- shape dynamics > angle jitter: 0%, control: initial direction - when using cutom shape brushes, setting the angle jitter to "initial direction" or "direction" ensures that all you brush strokes will seem natural and unique, and not all going in the same direction.
- other dynamics > opacity jitter: 0%, control: pen pressure - opacity based on pen pressure.
- smoothing: on
what i eventually did was make my own brush by making a small black paint blob on a piece of paper, scanned it in, and made it a brush. just something that looked like a paint stroke, had some dynamic shape quality, and some varying opacity. to make a brush (in ps cs2, though i think it works for other versions):
1. i made the paint blob the default size i wanted the brush to be. i made the document with a white background and the paint blob black.
2. select the paint blob using the marquee tool.
3. edit > define brush preset.
what i then did was apply those particular setting to my own brush. in addition, i also added a texture to make it look more like pastel or some other real media.
- texture: grass - this is a default texture in photoshop's library.
- texture > invert - i activated invert because it changes the granulation in a way that i liked.
- texture > texture each tip - applied the texture throughout the brush stroke.
- texture > mode: subtract - again, it yielded a result i liked.
texture is best to be fiddled with. it's also worth your time to try out photoshop's other preset brush collections, like dry media.
these are a few digital coloring/painting tutorials i've collected from the web, mostly from da:

this might be more info than you're looking for, but i guess it's worth mentioning. for blending purposes, like someone said, hot key your eye dropper, and also make a pallet of your true base colors (middle, base, shadow, reflected color, etc) so you can pick those out on the fly.
