Howdy,
I need to bring down the voltage I get from my LFO to a range which is more suitable for PWM. The LFO swings from 0 - 8.35 V, but I need something in the range between 3.49 – 5.59 V. So, how do I accomplish this? Dividing, clamping and offsetting all in one? Any ideas, schematics or pointers appreciated.

It's a relatively simple op-amp circuit which scales and offsets whatever to whatever. Search for Attenuverter.

Great, thanks Uncle! I'll have a look.
