A clutch alignment tool is very cheap (a couple dollars) and is available at auto parts stores. It keeps everything lined up when you bolt down the pressure plate, so your tranny input shaft will slide straight in. As mentioned above, you dont need it, but I would highly recommend it. Lifting a tranny up and down on your garage floor over and over because you cant get it seated is no fun.
You dont need the flywheel turning tool, so dont worry about that. I know I never used one anyway.
This is a great job to tackle by yourselves. Difficult and technical enough to be a great learning experience, but also rather simple at the same time.
