Needless to say its too long to post here. Local Home Buying Programs in each state. There is a whole bunch more but these should carry you over until you can get more knowledge for asking more specific questions. There is a mortgage calculator here that allows you to figure this out, however do not fall for the biweekly payment schedule that some banks offer. Biweekly payments are applied the same as all the rest of the payments: to principal and interest. If you are going to pay extra payments, make sure they are applied to principal only. This assumes you have enough income to deduct it and you do not fall into a lower bracket because of the dedcution.
