Crash Course for bartending?

I work at a restaurant with a bar that doesnt get too rowdy or busy and really the only people who sit there are our regulars. Well, three of our bartenders just quit/ got fired and my management decided to throw me back there for tomorrow because I learn really quick and im good with customers and I do a pretty good job. Im going to go in an hour early so they can show me some of the basics and then cross their fingers and hope it doesnt turn into a big wreck but I thought it would be a lot easier on them if I could do some research and have a little knowledge to work with. I dont really know (and i dont mean this to be offensive) what more there is to bartending other than pouring drinks. So I was wondering if any of you could suggest a bartending 101 website or something that would give me an idea of what im going to be doing or at least give me some kind of step stool so that I wont be completely clueless tomorrow. I am familiar with lots of alcohol but my knowledge goes as far as mixing jack and coke, on the rocks means with ice and a dirty martini means they want olive juice in it. Lol. Any and all help will be greatly appreciated. Thank you in advance!
