I don't have answers to your specific questions, but I did do a similar migration recently. I encountered one fairly significant hidden issue that I'll warn you about. When you migrate, you can leave your xml on the xworks dtds. It works, but as you migrate up the struts2 versions, there's a point where they moved the actual storage of the dtd's ( on the web I mean ) to apache. This causes the internal resolution of the dtd's to break. The simplest way to avoid this is to migrate your xml config files to the Struts2 dtds. Here's a link to my thread on this issue, but you don't really need to digest it all. You can be safe by simply migrating the to the struts dtd's from the start.
