I am updating woodlot polygons in ArcMap 10. Instead of editing individual verticies, is there a way to edit that is more like drawing part of a new shape (say if the woodlot has expanded only on one side). I'm looking for something similar to the trace tool but I'm working off a tiff image so trace doesn't work. I just want to trace the woodlot and have the existing polygon update to that new shape. Anything to make this task faster would be much appreciated!

You can use the "classic" snapping as well as editing environment in version 10. Look at the Editing Options dialog box.
Honestly, you're into a corner the API that not a lot of people are using so I'm not surprised there weren't many results from Google on this. Editing in a web app isn't yet an operation that a lot of people are using.
The issue is probably in the "tool" argument you're passing to editToolbar.activate. That argument isn't an array of constants but rather uses a bitmask. While clever, it is not intuitive or readable.
When you want to specify multiple operations, combine them with the | operator. This is documented in the activate method section of the edit toolbar docs. It's also shown in the edit toolbar sample. If that doesn't work, please post all of the code you're using to call editToolbar.activate.
Edit: here's a simplified version of the edit toolbar sample showing edit vertices + add vertices as well as rotate: http://jsfiddle.net/GKuhX/

Instead of moving individual vertices for a feature you can use the Reshape Feature tool on the Editor toolbar.
Depending on how accurate your polygons need to be you could also leverage remote sensing algorithms to automate polygon creation against aerial imagery that has 4 bands (fourth band that is NIR) or LAS lidar data sets, see:
