Best place to start is the Sanctuary Shop. This is in the LIVE Room, the one on the far right of the Sanctuary. Jasper stands by the Online Store counter, and DLC items are available on display behind him. Simply select the one you want, and options for purchase and download should appear. Once an item is downloaded, you may need to save, exit, and reload to get the DLCs to activate. Alternatively, you can get DLCs directly from the relevant marketplace: if you bought your game on disc through Games for Windows, or if you bought it through Steam. Hopefully that answers your question; if not, let me know what else you need.
