Javi,
I highly recommend the Revell 1/350 Bismarck.
Tools are problematic. Some existing household tool items may work fine like some small wire cutters that cut flat on one side, or needle nose pliers or sand paper in 100 to 440 grit and, of course, scissors.
Otherwise, here are a few tools that I started with.
Pin Vise, Sprue Cutters, metal files, needle nose pliers, tweezers, magnifying glasses, Clips and Clamps to hold parts, tape, more tape, good Lighting, rubber bands, Dust mask, good size table, and a cat-free area. I hope other folks will fill in things I missed on future Posts

There are "Kits" of tools but the included tools are not always the best.
Squadron.com has had a nice Tools page here: https://www.squadron.com/model-building-tools-and-supplies-s/2522.htm
Their pages will give you a good idea of the tools. I do not buy from Squadron anymore.. I've had no problems, just never anything there I need.
Good tools will last a long while and are worth it. Nothing worse than clamps that fail or magnifying glasses that ruin your eyes. I hope other members will post some recommendations for specific Manufacturers or name-brand items.
