Jerry, were you thinking of having a different thread for each subject?
SFA-01....Straight front axle, topic 1
IFS-01....Independent front suspension, topic 1
IRS-01....Independent rear suspension, topic 1
STE-WS-01....Steering, worm & sector, topic 1
STE-RP-01....Steering, rack & pinion, topic 1

I can begin with suggesting that those of you who wish to understand IFS should read Carroll Smith's Tune To Win. He has you making paper dolls in the back of the book, suspension segments made from construction paper and using stick pins to see how the system operates.
