How do I hook up two (2) Dell monitors so I can utilize them in a dual monitor application (laptop)

I have a Sony VPCSA490X laptop computer in which I use the Sony port replicator (docking station) – I recently purchased two (2) Dell U2410 monitors – How do I hook up the monitors so I can utilize them in a dual monitor application (in digital). The docking station has one (1) HDMI port and on (1) VGA port; each monitor has one (1) DisplayPort Connector, one (1) HDMI Connector, one (1) DVI Connector-1, one (1) DVI connector-2 and a VGA connector. What cable or components do I need?

If you could help me out, I would be so grateful.
