I am in the process of repairing the door latches in my 1956 Crown. I am also replacing the driver side vent window assembly. I have been told that everything inside the door has to come out. If anyone has detailed instructions on how this is accomplished, please let me know. I have removed the upper interior door garnish and the interior door panel. I have two specific questions on issues I don't know how to handle. 
1. There is a bolt at the bottom of the lower leg of the vent window assembly that I had to apply heat to remove. It is a slotted stud maybe 3/8 inch in diameter and 1-5/8 inches long. It had a nut and washer on the outside of the sheet metal and what appears to be either a threaded washer or undersized washer on the back side of the sheet metal. The threaded or undersized washer will not budge. I assume the slotted stud is used to make adjustments to the vent assembly. Is this bolt an original to the car or is it something installed to get by? Is a new one available?

2. There are two stops along the top of the inside of the door under the door garnish molding that are held in place with two clips. How are these clips removed and reinstalled? 

The best thing do is invest in a 56 Ford shop manual and also a 56 Ford body ,trim &sealant assemble manual by Jim Olsen ,all of the information you need is in them  Carl

Danny:  Replacing a vent window in a 56 Victoria can be quite a job.  I'm not trying to tell you to take it to a automotive glass shop, I think everyone who is interested in old cars should do as much as they can to get the full enjoyment of the car.  Having said that I second Carl's suggestion that you buy a Ford Repair Manual for your '56.  They are not real expensive and most Ford reproduction parts sellers (such as Macs, Concours, Tee Bird , etc.) carry them.  It will have the complete procedure for replacing the vent window.
Your are correct  that The "screw" with the slotted end is for adjusting the vent window.  It moves the window to the inside or the outside of the car.  There are more adjusting screws also but the shop manual will explain them all and even tell which way to turn the screw for the effect you want.  Its a good reference to have on hand for just about anything you may want to do on your Ford.
Carl, I don't think he needs the Trim and Sealant Assembly manual unless he plans to really get deep in restoring the car.  The only time I used mine was  for putting in a new headliner and some of the trim.

My driver door latch was loose on the shaft and I looked at everything I could to repair it. Finally held it where it belonged and heliarc it together. Never will come apart again but fixed. Driver doors never are as good as the passengers. Good luck
