You will never have a rotor on either side, regardless of front or back, that is equal in regards to thickness. There will ALWAYS be a variation from side to side due to rotor material and pad material. Neither of them will ever be a perfectly matched set. If someone is telling you that this makes a difference in regards to how your transmission shifts or operates than you should not walk, you should RUN AS FAST AS YOU CAN away from that shop!!! That's complete and utter BS!!!!!
A thinner rotor on one side *might* influence a pull on braking and even then it would have to be pretty severe in order to do so. It would not affect how the transmission operates in any degree whatsoever....
As to the OP, your steering wheel is wobbling because your front rotors have excessive runout and/or are warped from heat. You probably don't notice a wobble during the first braking exchange or at low speeds but once you get those front rotors heated up just a little bit the wheel starts shaking. Time to replace the rotors....
Get yourself a good aftermarket rotor with factory tolerences or bow down to the man and buy expensive factory rotors. Anything is better than what you have now but an aftermarket (read "reputable" aftermarket) rotor with factory tolerence will get you on the road to smooth braking.
Whenever you replace pads it is always a good idea to replace rotors also. Don't fall into the cheap trap of having your rotors "turned" at your dealer or at the local parts shop. You do yourself a disservice if you follow that line. The ONLY way to turn rotors the CORRECT way is to have them turned with an on-the-car lathe. This process at least accounts for the entire runout in the axle assembly and is the best way to turn rotors correctly. However... even that process still brings you to a point where the rotors on the truck are still thinner than they should be. The thinner the rotor the more heat they produce. The more heat they produce the longer it takes for you to stop. Thicker rotor surfaces absorb and dissapate heat more efficiently than thinner rotor surfaces....
Ten feet of stopping distance might not mean anything in your driveway but that ten feet might mean the world if it means not running over that 5 year old who just ran into the street chasing his ball....
