Well, what does your gear focus on? During Cool Ranch, I mainly focused my gear around damage, dodge, and agility. Dodge and damage will help you not be hit as often, and you can kill faster with the extra damage. I just added in agility because Stabby weapons boost from Agility.
Another thing is, what weapon are you using? Try to stick with Stabby weapons, or if you have Musketeer powers as well, Stabby/Shooty weapons. You will get the damage bonuses you get from the talent "Stabby Weapons."
One more thing. What is your companion line-up, and what epics do they have? The companion epics and line-up is totally up to you, but here are some companions and epics that I recommend having higher up the line-up.
Bonnie Anne should be somewhere near your firstmate slot, depending on if she is a sniper or sharpshooter. Get Overwatch and Burst Fire, and when she promotes to sniper, Burst Fire 2.
If you have El Toro *music*, train First Strike and Relentless. What you train him when you promote him is up to you, but I recommend either Relentless 2 or Blade Storm. If he appears in battle, use his buff the first round.
Sarah Steele is also a very good option. If she is promoted, train her First Strike, or Riposte, or Flanking. Any combination of those epics will do.

Hope this helped. I wish you good luck on beating Cool Ranch.
