I think I have the perfect combination of books for you which I use myself as well:
Total: 20 skill points
Raiding:Lockpicking - Level 7 (max)
Crafting ALL ammo, lockpicks and almost all props:Basic Crafting - Level 3
Weapon Crafting - Level 1
Machanical Craftig - Level 2
Ballistic Crafting - Level 4
Extra useful stuff to fill your skill points:Back-Pack training - Level 1
Herbalism - Level 1
Theft - level 1
I hope this helps
It will make you be able to craft and use lockpicks, ANY type of ammo, almost all props, and of course all the recommended books such as Back-Pack training to get more inventory space, Herbalism to join your friends in growing, and Theft in case someone left their shop alone.
