I can respond to the pricing piece – if you have some funds available and want to research this, I would look into a research technique called Choice-Based Conjoint Analysis [1]. This is a research technique that has you list out the main attributes (processor, for example) and levels within those attributes (1 GHz, 2 GHz, etc) of the product that you’re selling. You then send respondents through a mini simulator, asking them to choose between “choice sets” – different combinations of your attribute levels.

What you get is a preference score for each level. You can then build things like a pricing demand curve, or a full blown market simulator if you know what features your competitors include in their products.

It’s also great for assessing what features you want to include in a product.
