Picked up at Squier '51 and am hoping some of the more experienced fretters can point me in the right direction here.

I want to try the file the the ends of the fret wires thing. What should I use? (Probably a file, duh!). Any specifics would be appreciated, though.

The neck pick up is way crooked. Not "flat", higher on the front and bottom than the top and rear. I'm guessing this is not right. If I can put it down long enough, I will remove the pickguard and look for the adjusting screws. Maybe it is canted due the pickguard installation itself even. Sound reasonable? But I also noticed the 6 small metal pencil eraser type of things (sorry, don't know what they are called) sticking out of it are also not "even". The top one does not protrude at all and 2 others extend only about half way out, as compared to the 3 that seem to sticking out all the way and are even? Is this normal?

Thanks in advance for any insight....
