Ok, so I have access to Adobe Premiere 6, and After Effects 6.5. I was wondering how I could make a video with one person in multiple shots (with a tripod), and then merge them all together. My friend knows how to do it, but it won't work if the shots have the person crossing their own path. Anyone know how to do this?
Movie Editting, multiple "clones" of one person
Okay if you know how to work with photoshop this will be easy for you.
First shoot all your shoots back to back to back, I usually don't even stop the camera (you can just edit it later).
Then import the footage into after effects and put all the images on top of each other. Then you want to make a mask and keep only the person in each (leave the whole back ground clip alone). Actually if you are good enough with masks you can have a person cross paths.
Check out my video for an example:
It is the middle one:

It's not loading...
anyway, I understand masks in the GIMP (similar to photoshop I'm guessing), but I don't have experience yet with After Effects, if you have to mask a person, would you have to change it for every frame that they move in? Sounds like a lot of work, but I may try it. Just need some more info please.
You don't necessarily have to make a keyframe each frame for the masks. You could try first going every 5 frames or so, and let After Effects fill in the rest by itself the best it can. However, it is likely you will have to add a keyframe nearly every frame to get it to look right anyway. Also, unless the person is directly "touching" another person or is "walking behind them" you don't need a detailed mask. A simple rectangle will do fine.
Another thing you could do would be to take a still image of your empty background, then using additive masks, add all your people on top of that.

It's called rotoscoping and if you want to do it right, it is very tedious and time consuming. The easiest way would be so shoot the initial shot of the person on a greenscreen. Then you can add the background later and put as many instances of the person in as you want. They do this in movies to "fill a stadium or make a concert." There was just a tutorial up on Apple's pro website showing how they used Trapcode Particular to "clone" a group of about 5 girls dancing in front of a greenscreen into a entire concert audience.
I've done some rotoscoping (masking people out of a non-greenscreen shot) and boy does it take some work. I masked out one basketball player so I could add some light rays to him and black and white the rest of the background to make him stand out. I did about 3 or 4 seconds and it took like two days of steady work for me to do it. Of course I didn't have a tablet which would have sped the process up a little, but it is a big chore for sure.

Shooting the talent with an evenly lit green or blue background and using chroma keying in After Effects would work, no hand rotoscoping. There are online tutorials/tips for both shooting with green/blue screen and for compositing the footage in After Effects.
As far as traveling mattes or masks as they are called in AE, they only have to be tight during the crossover part.
All this is assuming your camera is on lockdown with a background frame that doesn't change at all...

I've done that before putting the same person playing every position in baseball. All I used were simple oblong masks but as people have said, a crossover requires a tight mask. If you are doing this outside be careful as the sun may move just enough to make the shadows change in the time you move from one position to the next.
