Best advice I can give is if you get a job as a bouncer always listen to the bouncer who's the smallest (and generally has a shaved head and pristine hands). I remember hearing about this guy who was a bouncer as a second job near where I lived. In the day he was a carpenter so he couldn't risk mashing his hands up on the job. So he used to to just drop the nut on anybody who caused him grief. Cause he was so small folks wouldn't suspect him at all. I think MA training would be a must. At the gym I used to tarin at w there were a load of massive guys who looked the part but couldn't fight for crap. I used to watch them on the bag and laugh at how ridiulous they were. Gotta say though I'm not adding anything productive here so I can only agree with Bobby135. All you need is good common sense and an eye for percieving potential trouble.
