I'd suggest supporting the cab, cutting the old floor out but leave a 1/2" of it uncut every 8" or so. lay the new floor in (don't use the whole pan... Pro-Body pans arent the greatest at the trans tunnel/ seat hump) tack the new pan in, then cut the rest of those 1/2" peices off. Fully weld and your done. (Don't bother welding it in front of the doorjamb if your just gunna cut it off anyways)
Pass. side I wouldn't worry about a new floor by the looks of it. Some 16g will do just fine.
Note: Don't butt weld floorpans. Leave a little overlap and fully weld/seamseal either side.
