Installment util is counted separately from revolving util (which is the biggie), so don't worry about the SL and auto loan for now. Get all the cards under (not at) 30%, with a goal of getting them down even further. If you have any cards with relatively small credit limits, you might set a goal of paying them off completely and leaving them that way. It's a bunch easier to PIF a $500 CL card with 30% util than a $10K card with 30% util!
Paying off the car loan more quickly makes sense to me. Cars don't always last as long as car loans do.
