All great advice...if it's a direct replacement...if not, then it's just cutesy tripe.
If you have to do any drilling to mount the new bridge, then you probably have to also do the following: make sure the center of the bridge lines up with the center line of the neck; that the bridge is positioned so the saddles have enough travel to set the intonation properly, that you don't mount it crooked. And make sure the new bridge makes good contact with the grounding wire. And that you drill the proper sized holes for the screws. In the unlikely case that the bridge is taller than the old one, you could even want to shim the neck...highly unlikely, but the point is that, depending on what you're planning on putting on there, you'll have more considerations. THEN you can read all about intonation and action.
I don't have any good links for you yet -- I'm working on a project bass right now and only have an odd bridge to use that is skinnier than stock, and completely different mounting holes...but I don't have a tried and true approach -- I'll just be doing a lot of measuring, marking with tape, remeasuring, etc. and then eventually some drilling.
Good luck!
