Okay, here we go. ;)
Showmanship is when you walk beside your horse, is usually considered 'western', and you have to spin your horse, stop, and trot. The judge will evaluate how well your horse listens and performs. :) This is done in a halter. If they have an english showmanship class, then you do it in a bridle.
Horsemanship is when you ride a pattern, and YOU are judged on how well you ride. This is a western class.
Equitation is when you ride a pattern, and you are judged on how you ride... this is an english class. ;)
Halter is where the horse is judged on conformation.
You should have 4-H classes in your county (Just google your county and 4-H). A lot of states have a State show association; like the New Jersey Horse Show Association where everyone can show there too. :) And your horse doesn't need papers for either. 4-H will have a state and national classes.
Hope this helps!
