Help with spawning, pathing, and GUI

Hi, I’m new to Unity and have just about all the level design aspects down, but I need help with spawning and GUI. If anyone could explain or link me to some good tutorials on those subjects I’d be grateful. To get a little more detailed, I need to know how to spawn enemies and path them to go after the hero, as well as give them guns since my game is a FPS. Also I need to give the hero a health and armor bar, as well as give him a few guns. I know some of this will probably need to be done through scripting, but I don’t know where to begin.

You should probably begin with the FPS tutorial.
