It is pretty self evident what you will need to do once the door panel and plastic moisture barrier is off. You can move the window up and down with the glass out to get it into a good position - then clean and attach. Don't assume you have to pitch it if the channel is corroded. I have been driving for five years with both of my channels on the edge. However, they are gooped up and work just fine.

I would use real silicone or the 3M weather strip adhesive. I think the silicone will repel water better but the 3M adhesive is stronger - my opinion only.
