Thing I always do (with SA-MP projects at least, including this project) is first try to create what you want to achieve and see if it's even possible. At that stage you're creating a proof of concept, so your code will not and should not have to be perfect. If you you ever complete that stage, then worry about packaging it in an include or whatever suits the project best.

To point you somewhat in the right direction, I recommend using the latest FCNCP pre-release. Support for NPC pathfinding will be implemented in the future, so don't worry about that part. If you decide to use my include, I recommend using the in-development 2.0 version, which has some significant improvements over the latest stable release. However, I don't know if using this include is the best choice for your use case, you'll have to experiment with that yourself.
