man you gotta remember that when you step in the cage/ring, you're fighting against people who have been crossed trained and most likely are capable of taking inmense damage. If you live in cali, there are tons of places to train, and many amateur mma shows here. In training to be more specific, you'd have to mainly crosstrain in jiu jitsu, wrestling, kickboxing, and boxing. Crosstraining is very good because you will get used to how to take a punch, will be able to trade, defend yourself when youre on guard, get excellent cardio, etc. If you've watched some Pride Fights(For example, Final Conflict. Minotauro vs CroCop) CroCop would have to wait for the referee to stand up Minotauro because he had no ground experience, and got in deep trouble once he got taken down.
