obviously, a plasma cutter, but those get to be expensive, and not many people have buddies that heve em. You can use a pneumatic jigsaw, an electric jigsaw, a saw zaw, or a pneumatic cut off tool. I have listed them in order of easiest to pain in the butt to use

Pneumatic cut-off tool. You can't get the same precision with the others(except plasma). The cut-off wheel gives you a nice clean line to measure from for butt welding. If you aren't butt welding then you can just hack it with whatever, it doesn't matter. +2 on the good spot weld removing bits, you will need them.
I have done a lot of floor/frame rail replacement, and I would say the plasma cutter is the worst tool to use. The problem is, for a plasma cutter to work you need a good electrical connection, or ground. Since you are cutting out rust, there is not a good connection for the plasma cutter to work. A cut-off tool, and a torch is what seems to work best. I have used many brands of spot weld cutters, and they really don't hold up, I often rely on a good quality drill bit set.

Agreed... I have a plasma and that is the last thing i would use to for floorpans.
I would use a nibbler if you could... then a jigsaw...then a radiac with a cutoff wheel or grinder with cutoff wheel. They are pretty simple to use but sparks suck.
