window repair

First time I have done this and have not opened it up yet, just looked at the mechanism online. My manual drivers side front window dropped out of the track while being rolled down last year. I kind of manipulated it back in and have left it rolled up. I want to go in to fix it, assuming...

Have seen some special tools online for removing/working on the upholstery on cars. I need to remove the door panels to get to the windows. Do I need these special tools to do this? Also what comes off first? Thanks, E
