I see you are in Arkansas, there is a show in Fayetteville the first weekend in November at the Washington, County Fairgrounds. It is a good show with some very good quality birds shown there and you'll probably see some very good cochin bantams and maybe even a few Japanese bantams as well. There is a much larger show held in Shawnee, OK on the 2nd weekend of December where you'll see 25-125 japanese bantams and 50-100 cochin bantams depending on if a breed club holds a national meet or not. This show typically runs 2800 birds total so there will lots for you to look at.
I certainly recommend getting a copy of the APA and ABA Standards. Study your breeds and selected varieties within those breeds and when you get to the show talk to as many people showing your chosen breeds/varieties as you can. I'll be at both shows and will give you all the knowledge I have on the two breeds you have listed.
Keep a note book with you and take notes as you can, it is often hard to remember everything from a conversation weeks later but if you write it down you have it forever.
I wish you all the best in your showing endeavor.
