Do the negs look normal when proofed or printed at your normal printing times and filters?
If so, they are normally exposed and developed. If not, they are not.
I'd start there, then once you are set, worry about how to tweak things to optimize for scanning...and when you get there, you can ask at Hybrid Photo dot org.
However, the rule of thumb is to shoot and develop for a neg that is optimized for darkroom printing, unless there is absolutely no chance in hell you will ever print the negative optically. It is generally easier to scan a neg that is optimized for the darkroom than to print a neg that is optimized for scanning.
