an alignment is not what i think you need. go to discout tire or similar tire places and just get your front wheels balanced.
if that doesnt fix the problem look into replacing your front rotors and pads. its super easy. air tools not required!
drumsy pretty much summed up the install. and if your rotors are screwed in, your gonna need an impact-driver. when/if you do have screws to remove, you can just throw em in the garbage. your rotors will be held on by your lug nuts anyway. good luck, and keep us updated.
