Scotty, noticing that you joined recently and that you're worried about fuel management and a checklist, let me suggest you visit my "backup" web site at
www.SkymasterUS.com.
There is a whole section on fuel management for Skymasters like yours with separate auxiliary fuel tanks, where it reminds you that the fuel in auxiliary tanks should be used in the middle (not the end) of a flight and is not normally available if a main tank runs dry; a round-about way of getting it is presented, but it involves a complex procedure requiring that you first cross-feed.
And I have a one-page checklist similar to the one described by Ed; it's available to you through the web site.
