The Append Query is pretty easy. Just do an Unmatched Query between the two tables (joining on the Ticket Number field). This will show you all the records in one table that aren't in the other. Then just change the query from a Select query to an Append query.
For the Update query, you just want an Inner Join between the two tables (to return all the records that match). Then change to an Update query and decide which records you are going to update.
I would recommend reading up on Action queries (specifically Update and Append) in the Access help files for more specific details. There are also some tutorials and articles on-line that you can find using a Google search.
Give it a shot, and if you run into specifc issues, post back here, along with your code (if you change your query to SQL view, you can copy and paste your code here).
