I don't have any experience with removing a gas tank (1930 deluxe coupe here) and thus do not know if you have to remove the steering column as a part of that job.
I did fully remove and refurbish my steering column/gear unit in the course of my general restoration of the car and it wasn't that bad. It was about a year ago and as I presently recall, it was a matter of removing the starter, disconnecting the drag link from the pitman arm and then the pitman arm from the steering gear, disconnecting the spark and gas rod linkages, removing the light switch and the little "key" that holds the spider on the end of the horn rod, removing the trim plate on the floor/firewall around the column, disconnecting the clamp from the gas tank to the steering column inside the car, pulling the steering wheel loose but not removing it from the column until I could get the steering gear out of the frame and the whole column lowered sufficiently to remove the horn rod and then following that the steering wheel in its entirety, then just a matter of lowering the whole column through the hole in the floor and out from underneath the car. Lowering the whole column out through the floor and from under the car would probably be easier with an assistant, but I actually did it by myself. I forget, but I do think I had the front end jacked up a bit, but I did not have the car on a lift or anything like that.
