ITS REALLY EASY!!!! even to recover your seats. the headliner would be difficult if you've not done one before so i would hire that out but the rest is straight forward as the others have said! the seat are easy as well.
just toss the covers into the dryer for a few minutes to make them pliable and then slide them on over a plastic garbage bag if your afraid of them getting caught. you can pull the bag out after your done and then hog ring it in place. start with the middle of the seat and work it out and around to the other side. this will keep the cover fairly centered once you've gotten it set to begin with!
the only tool required for the carpet is a scratch all for the holes and maybe a box knife for the bigger holes. poke the scratch all through the hole in the floor underneath and come into the cabin area and cut an x into the carpet for the bolt. make sure the carpet is centered and straight and where you want it before doing this. also you may want to secure it with the sill plates. use the old ones so you don't ruin the new ones your replacing them with! the headlines is nothing i can explain on here. just done from knowing it.
overall this is an easy do-it-yourself project you can involve the kids in. they can help you with the bolts. placing the seats in and installing the carpet as well! hope this helps a bit!
