You can do it before soldering if you keep it away from the pads. Just as well to do it when you are finished, like misterE said, it will smell
Ive always been told never to file a soldering iron because it wont work properly. Something about the heat not being focused to the point or something. Ive not seen anywhere that sels the kind of tips the old one uses. I could do with a new really expensive one from Rapid that will work well.
If you are careful you can get away with filing. You will need to "tin" the iron afterwards. The main problem with filing is some of the tips are only copper coated, if the tip is solid copper you will be fine. File in the shape of "V", not a long point like a needle.

Traces? Should that have been "tracks"? Do you mean you flux the whole thing but only put a bit of solder on the pad or do you put solder on the whole thing too?
Traces , tracks . All the same for me.
Sometimes I only tin the pads and sometimes I tin the whole thing. Solder will not corrode as fast a copper. So it all depends on the job.

There is sometimes a problem with tinning, but you can have that problem no matter what because you have to use solder. That problem is the dreaded "Tin Whisker". But I think sealing the board after all is finished will help to stop the whiskers. Maybe skimask will chime in on that subject.
