Regarding #2, my standard recommendation is Don't Just Roll The Dice, a free e-book that covers the territory nicely. You can find it here: <a href="http://www.neildavidson.com/dontjustrollthedice.html" rel="nofollow">http://www.neildavidson.com/dontjustrollthedice.html</a>
Don't underprice yourself too quickly. Price has a signal effect, and is viewed as a proxy for quality. You should definitely aim to make money even on your early customers.<p>Regarding #1, there's no magic-- just total up the expected expenses, and leave some breathing room.<p>Note: the only relationship between #1 and #2 is that you want to make sure your price exceeds your cost. Otherwise, the price should be independent of your costs-- the key factor is the perceived value you provide the customer.
