If you want a default select for your parameters then you can set that up in the "Default values" section at the bottom of the "Report parameters" screen. If you want just one value chosen then you can use the "non-queried" option. for example, if you wanted toady's date selected then you would enter "=today()". If you want to select a bunch of stuff (or everything) from a query then you can do that with the "From query" option. It will ask you for a dataset and and a value field that matches the value field from the "available values" section.
