I was going to do this as my leg workout tomorow (maybe add some calf raises afterwards also) Has anyone done this before and how did you find it? Im a bit scared really

It's a bad idea, lower back fatigue can cause an excessive forward lean and cause some serious damage. Be very, very careful.
Squats and deads on the same day are great. The workout is hard and will take time to get use to but if you can take it, it is a great way to train.

I've supersetted Stiff Legged Deadlifts and back squats before, but I went very very very light on the squats. My squat max is 270, I think I hit 135 to 180 that day and used 2 30 pound dumbbells on the SLDL's - a moderate weight for me at the time. My whole body felt very weak afterwards, but that was just about all I did that day, so I guess it was ok.
supersetting=doing one set of squats, going over and doing one set of dead lifts, one squat, one dead lift,etc. great on some body parts, but not in this case.
so like..for example..
1 set of flat bench press
1 set of dumbbell flyes
1 set of flat bench press
1 set of dumbbell flyes

A superset is simply two exercises done back to back with little or no rest.
There are two common ways to do it. You can do two exercises that hit the same muscle or muscle group. Such as you example of doing flyes with bench presses. The other way is to hit the agonist and antagonist muscle, such as doing EZ Curls (biceps) and Standing Extensions (triceps).
I often do supersets with squats then lunges. It works great as it hits both the quads (mainly squats) and hams from the lunges. It feels great and by great I mean having to use the handrail to get up the stairs three days later. It works.

I'm going to throw some theory in here because I've never done this before. It seems to me this would be a good cardio/vascular workout, but not so good for either your leg or back development. You're talking about two HUGE lifts. The amount of exertion required to do a single set of EITHER exercise wouldn't leave enough in the tank to perform a worthwhile set of the other exercise. Now I'm obviously talking about acheiving muscular hypertrophy. If you are actully looking to increase cardio/vascular stamina then go ahead, it sounds like a good idea.
