If players want to try a PrC, take a look at it, see if you think it would fit, and make a decision then. You don't need to be aware of every PrC before you start a campaign.
Well, when the players are trying to build their chars, and are angling for a particular prestige class down the road, you have to be aware of at least that particular PrC so you can decide if it will fit your game down the road. Again, i'm not complaining, it's part of being the DM.
However, it does require more "paperwork" (for lack of a better term) to sort through all of this.
The best results we've had with PrCs in our group is when players come to me with a PrC and say "I like this, can we use this". Since I'm a stickler for PrCs fitting in the game world, I usually question them until we distill down what they like best about it, then we cooperativley build a new PrC based on those core elements. The results have been very good PrCs, which are balanced (crunchy) and fit the world (creamy). This works great and the process has been a lot of fun. However, if I was tasked with doing that on my own, it would have been probably more than twice the work (meaning time) and the players probably wouldn't have been as happy with the results.
Again, I think this illustrates the point that at least for the DM, 3E is more complex because there are so many options. Sure, I don't use them all. But unless you at least try to accomodate your player's wishes, your group won't last long. Like I've said before, being a DM requires lots of time, and I'm happy I am able to devote the time to it. However, it sure seems to me that it is more complex and harder to DM than 1E.
