For lighting do not waste your money on the replacement headlights from Baja Design.  They provide better lighting, but not enough for the price.  Better off with a set of XL80s on the a-pillar and a set of XL80s or LP6s on the bumper.
Paddle tires talk to 
@megadesertdiesel.  He runs the Packard sand tire set up and seems to love it.
Cages - if you are in AZ,  SDR is there and makes a nice simple strong cage.  UTV, Inc and Brick City also make nice cages. There is also Cab Fabrication (Jesse) that makes some really nice stuff.
