Regarding the tools

You can:

• find tools in various houses in villages, such as Montera;
  
• get tools when beating up NPCs using those tools currently. Find a slave who uses one of these tools and keep beating him until you have enough. Just let him get back to work first, NPCs always invoke into their inventory the required item when they want to interact with an object.
