The first is video board that will drive two monitors. The second is for more USB ports. Eight(8) would be nice four(4) would the miniumum.
 
Normally the integrated video on the motherboard will drive two monitors.

More USB ports can come via a add-in card if you have an expansion slot.
Or, there are USB hubs that can give you more ports.
Can you supply a pic of your motherboard?
Or, a link to it's specs?
