In your Sandbox, create an Outbound Change Set (Setup->Deploy) and add the classes, tests, and other pieces you want to deploy. When the Change Set is complete, click Upload, and pick the Production org.
Once the Upload is complete, go to the Production org under Setup->Deploy->Inbound Change Set and Deploy it.
If you don't see Production as a target in your Sandbox, you'll need to setup a Deployment Connection in Production (Setup->Deploy) to authorize Change Sets from your Sandbox.
