What do I need for a tune up

I have a Jeep Cherokee Sport with the 4L distributor less system. I think it is, there is nothing on the left side (facing the engine) of the engine block when compared to my 1993 Wrangler 4L engine. What would be a complete parts list, given the mileage and not having had a tune up in a few years. I have spark plugs, but should I replace the coil (what kind) and spark plug wires(if they are utilized). I'm sure it's obvious I'm not a mechanic. I'm getting the work done at the auto repair vocational program at the prison I work at.
