737 checklist:
-Preflight checklist.
-Before start checklist.
-Before taxi checklist.
-Before take off checklist.
-After take off checklist.
-Descend checklist.
-Approach checklist.
-Landing checklist.
-Shutdown checklist.
-Secure checklist.
Guess 747 will have same structure, with different items on each checklist.
If the Virgin checklist you have seen, has these steps, then is complete.
Each company may include different items. The best you can see to have a real idea is the "Boeing standard checklist".
Probably you will find some pic or list on internet.
