1) Yes... but no more than Seymour, Aero, etc. Very nice pickups with their own tone profile that many like.
2) You will notice a difference (a bit warmer, a bit smoother, a bit fatter, a bit less aggressive than what most consider a classic Fender tone). If you like the difference, you will hear it as an improvement
3) The Audere is pretty subtle and will not 'cover up' the tone of a given pickup, so IMO that's a moot point.

Gotta agree with KJung - they are a damn fine set of pickups, but a lot of manufacturers have great sounding sets of pickups too. The NJ5F's I had paired with an Audere had a very nice growl - a very warm growl in the lower frequencies, not a 70-ish aggressive jazz, upper mid growl, but very nice just the same. Also had excellent note clarity as others have stated.
