Re: replacing individual saddles?
When get a guitar, I recondition the fretboard and restring it (you never know the crud/bacteria factor). When the strings are off I flip the two middle saddles (D and G strings) so that I can get extra travel room forward for the D and extra travel rearward for the G. I use a small flathead to pry off the retaining wire, and with the saddle screws positioned in the middle of the bridge, they come out easily.
