i see you drive a 2010 se. do you know if that was ordered with abs?
ive got 130k on my factory equipment and a recent inspection has showed ive only used half of the pads and the rotors have no scarring and thats with "spirited" driving and some track use. so your mileage should have nothing to do with it.
now as for the rear end bucking there could be a few things to look for. a bad absorber or a bad control arm bushing. the latter is hard to diagnose and to find out you need to remove it from the car. not a hard job- you should be able to do it in the driveway but remember that there is a great deal of spring pressure on it so you may want so coil compressors. you can get that at harbor freight for $16 or borrow it from autozone for nothing...
a shaking steering wheel could be from a warped rotor but that alone will not make your wheel shake as you have floating calipers. the rotors could be heavily warped and as long as the caliper can follow the profile you would never notice any performance loss.it is when the caliper binds up on its slides that you feel the shaking. grab a can of caliper grease and brake cleaner then disassemble the caliper. remove the slides and wash them with the cleaner and make sure to clean the wells where the pins ride in. then grease everything up and reassemble. there are also some stainless slides for the pads scrub those down and slap some grease on them too but make sure not to put too much on as the excess will get squeegeed of and most likely will end up on the rotor
