bitbake-layers show-appends will give you the former. Patches get applied 
strictly in the order they appear in SRC_URI, if you have bbappends that 
append or prepend that variable that will of course influence that, but the 
final value and hence the order should be visible through bitbake -e recipename 
| less and then search for ^SRC_URI (along with history of how the value came 
to be).
