It sounds as though you are quite early in the process of making a game on the platform. A lot of the basics would be covered in a book on the subject which will take you through the steps one at a time.
A good such book is "Beginning iPhone Games Development" available from Amazon.

Alternatively you could have a look at the code examples Apple provides. The Move Me example is a good starting point as it shows both user interaction and the movement of objects.

Good luck and, above all, enjoy.
