You can stop the PC from taking any of the prestige class, during any of the levels up. All you have to do is set a Local var on them to 1. The local Var to set will be listed in the cls_pres_*.2da.
For example in cls_pres_harper.2da line 6 is:
6 ScriptVar VAR X1_AllowHarper 0
It basicly states that in order for the PC to be allowed to take the class they will have to have the X1_AllowHarper local variable on them at 0. If it is set to anything else they will not be able to take the class.
If you are using haks you can also make the Base classes work the same way. The PreReqTable column in classes.2da points a list of class restrictions, You would just have to add it for you base races.
EDIT: I do believe that shadow has stated that he has already done this in the 1.70 patch.
