This has to be the easiest rally for a newb to do self-sufficiently. Fly to Reus, hire a car, rent an apartment in Salou (huge choice). Get itinerary and use google maps to plot route. If you have a travelling companion the car and accommodation are halved in cost! The organisers post thorough stage guides well in advance. Just remember that any iconic locations such as El Molar hairpin fill up 3 hours in advance of 1st car.
