The if the tie rods are parallel to the chassis that is just barely ok. The ball studs at the servo saver should be just a little lower than at the steering spindles.

If you use the holes on the servo saver closest to the servo saver cylinder (you will have to file flats on the servo saver cylinder where the ball cups interfere with it) and use Trinity long offset pivot balls. Then tie rod angle will be correct. You should have absolutly no bump toe in on a properly setup 1/12th car.

Do a search for pics of Josh Cyruls C-12 and you will see what I am talking about.
Well I can agree what you say of how to get rid of the bump steer but I don't necessarily agree that you should not have any. Bump steer can be a tuning tool to get a different things out of your car. I know many races were won with cars that had a ton of bump in. It helps the car get into the turn and gives more steering slightly in the middle of the turn. Sometimes bump in is good sometimes it is not. I was also testing servo up and down for quite sometime. For carpet in High traction servo down is for sure better. In low traction carpet servo high is faster. I am not exactly sure why but this is the case. I have never tested on asphalt but I would imagine servo up is better more because even when the fast carpet guys go and run asphalt they move it up to angled. Just my opinion and could be wrong but this is what I have found to work for me. So you might just want to try it like you have it and make some changes and see what it does. There is a possibility that something about your setup or the track you are racing on, one way works better than the other.
