Check out the Repository module (is one of the default included modules). It lets people submit items, you can approve them, and they aill be displayed in various orders. There is a small dashboard module with it that lets you display a selecting of the items on another page - eg the homepage. The Repository has various templates included and each one has different functions. The module also allows for comments and ratings and would probably fit the bill well.

User Defined Table module (UDT) could suit your needs, and it's pretty easy to use.

Otherwise, a third party module, such as xMod, would be well suited for this.
