I've found peppers to be finicky in comparison to their tomato cousins. Eggplants (another cousin in the nightshade family) are somewhere in between the two in terms of being particular about conditions for germinating, growing, and producing fruit.
freebs - as far as sowing seeds, the seed packet should give adequate directions for depth, light, and moisture requirements. In general, plant the seeds 2 or 3 times deeper than their size. I make indentations with my fingers, drop a seed or two into each crater, sprinkle potting mix on top, press down to bring the soil into contact with the seeds. Tiny seeds are usually sprinkled on top of the potting medium and pressed into it (not covered at all). A few seeds require light to germinate (such as impatiens) so those are treated the same way.
I usually bottom-water to ensure the containers don't dry out. Buy a few plastic gardening flats without holes, make sure your sowing containers have drainage holes in the bottom, set the containers in the flat, pour water in the flat, let the soil absorb the water through the drainage holes. Osmosis takes care of the rest. If you don't want to spend the money on flats, old aluminum pie tins work, or any plastic container without holes you can find, such as used for some produce, deli, or frozen food products in the market. Reuse then recycle!
