setting up 2way Direcway Dish

I have moved from Southern Utah to the Dry Tortugas Islands west of Key West, Fl.  I am going to attempt to set up my 2 way satellite dish but I am unsure of a few things.  I don't know what satellite that I was assigned to in Utah but would like to use the same one if possible.  I live about 200 miles from the nearest installer so I want to do the installation myself.  I bought a birdog sat finder, but don't know which satellite to shoot for.  I am also unsure of how to find the different angles needed for my location.  I have a 6000 modem.  I am at N 24.37.580  W 82.52.397.  Can anyone help me out?
