Can someone recommend some good adword keyword sites that will help me choose some good keywords. Is there a way to check how much the top spot costs for the keywords? Thanks
By good are you looking for low cost or high volume? Anyway, jump into the keywords/traffic estimator tool in your Adwords account for a rough idea of potential traffic and prices.
Wordtracker can give you some low volume (which should be low cost) keywords and phrases to get you going too. They have a free trial.
