that doens't sound like a pre-runner just like most of the troops on this board, if you can do fibergalss work you can do the fenders, skids shouldn't be too hard, a prerunner bumper, if you don't feel like makin it i bet stinkyfab would like to make one for an 0G troop, and the rest is history documented all throughout this site, don't count on any down travel once you lift the front end unless you're gonna make a lift yourself that involves resetting the xmember, also i don't think you're gonna get a lot of power outta that four banger, might wanna look into an engine swap, people can point in the right direction with that one

good luck!
totally doable, just might require a little more time and money than you originally thought if you REALLY want a true prerunner set up.
