The initial question?
No; you don't need a lot of special tools, and most of them can be make-shift/expedient.
1. Depriming; If you ever had an old LEE LOADER set, grab the de-priming punch. If not stick a nail in a dowel.
2. Repriming; A metal surface and a hollow pointed punch. Some use a deep-socket. I use a 4" piece of copper plumbing. You don't want to deform the primer pocket. When you can, get an RCBS shellholder and reprime on an "O" press.
3. Powder and shot measures ; Get a LEE scoop set. If you have a scale, and you should, you can make a set of measures from range pick-up shell casings
4. seat wads with a dowel.
5. seal/secure the load with Elmers glue over the O/S card.
Circle Fly is your wad source, but a 3/4" punch and scrounged card stock can get you started. (Picture frame shop card, cereal boxes, pulp egg cartons, waxed card milk boxes, cork gasket material.)
