Hi Adam, I think you need to work your way through the manual.
You can view clips in thumbnails, add the ones you want to a timeline, then in the colour page grade them. Even copy grades from one or two clips prior with a single keyboard shortcut, or copy from any clip.
You need to do this in the colour page as there are multiple ways and tools to grade so you need to have the correct one selected.
Then render the clips on the deliver page to ProRes. Use the FCP preset. All this detail is in the manual, including a tutorial. I can also recommend one of the many online classes available, such as Warrens on FXPHD.
