If you want something quick, dirty, and effective I'd look at
this set. I've seen it and McCann shows some great material (the striking portion is excellent) including some simple arm-bars and chokes. He also covers some good weapons defense stuff (gun disarms, knife defense, etc.). This is an excellent set. (you can probably find it on e-bay or amazon for less than what paladin charges)
If you can find somewhere to train, I'll agree with those that recommended some form of MMA training (boxing, wrestling, BJJ, etc.).
