Default question about biasing

how do you choose values for biasing transistors? i've looked and read thoroughly through several websites but have not been able to understand it clearly.

any help is appreciated

Stick some common values in and change them as required for your circuit. It's nice to have the pot centered for the desired bias but not manditory.
Use a variac for startup until the values are close to what you want. A light bulb will work if you can't get to a variac.
