Need help on how to fix interior rust

I removed the carpet to replace it this weekend. Unfortunately I found a rusty surprise on the passenger side floorpan. I was hoping someone could give me some advice on how to determine if I should replace the whole pan or not. If I dont replace the pan how is the best way to fix. I plan on doing all repairs myself. Complicating matters more is the welded-in roll cage. Check out the picture to see what Im talking about.
Thanks ahead of time for the advice.

If its just rusted enough to flake off the paint and not pitted to deep you can go to your local autozone if you have one and get a small bottle of rust converter, can't think of the name off the top of my head, but its in a small white bottle, 6 or 8 ozs. I think and its in the paint section. you clean the rusty area the best you can and then brush this stuff on and it will kill the rust and convert it to a black primer. I use it all the time and its some really good stuff. its only 3 bucks and its a life saver sometimes. But if its pitted real bad to the point of almost eating through, I'd go ahead and put in a new pan. Hope this helps

Well looking underneath the car I see no sign of rust eating through. I can smack on the bottom (or top) of the floor pan in both the rusted area and any non rusted area and the sounds I hear are the same. So I am pretty sure its only on the surface of the pan. The only area I am unsure about is the area under the roll cage mount. I have no way of knowing how bad it is under there.
Maybe I will have to fire up a torch and remove the welds?? Then I should be able to tell for sure....

Has anyone here every replaced a floor pan? Is it very difficult??
