vibration/steering wheel off ceter

ok, here goes it, I swapped in dx knuckles/hubs for my swap, it came with rotors attached they look in good shape and my pads are about 50%, after driving I have found that when I brake there is a grinding scraping noise, now the noise is constant at low speed and is worse when I brake, could this be anything more than just needing brake pads? also, idk much about suspension, but i installed a set of upper control arms with adjustable camber, i know i need to get it aligned, but after i installed the control arms the steering wheel is off center, will that be remedied by getting the alignment?

as for you vibration and steering problems an alignment would definatly help. where ever you take your car tell them about the noises you could have bad wheel bearing and warped rotors but have them check the brakes while your there and they will tell you what the problem is for sure.
