Hi ARSHIA First, did I see you have already joined fpsc Discord? If so great!
Sorry so long for an answer, but hardly anyone comes here anymore. Your first question, yes its very easy. There are several demo examples in your mapbank folder.
One under "samples\waypointmultilayer and another under tutorials/waypoint demos.
Also, I have several video tutorials for basic waypoints on my channel

Making models fpsc ready is a little harder than you think, have you use any 3d modeling software before?
Do you know how to texture and make UV maps for the 3d mesh?
