It sounds like you have a strong enough background to start looking into time domain filters. Please look into FIR and IIR filters - they are much cheaper to compute and can do everything you were asking about. Please share your results.

I've done the "FFT -> throw away stuff I don't want -> IFFT" method before. It is waaaaay too draconian, and has really nasty artifacts. I'm not saying it is impossible, but it can have some really wonky side effects.
