help any info

This is a standard Tribute guitar, comeplted on April 7, 2003.  
 
Is this a guitar you own?

just got it, it has never really been used, i want to replace the tuners to locking tuners what should i use that wont dammage the thing to much

i also would like an explanation for this next issue, the frets are untouched so this is how they left the factory, the crowning as you progress up the neck is different, from fret 1 to 12 the frets are flat crowned and then the rest of the way up they are rounded.why?
