I, me and myself. Which one to use?!

Most of us might have faced this confusion at least once during preparing a very formal business communication. Hence, the anxiety of committing a grammatically incorrect choice!

The key is: 
    1) Remove the  accompanying subject and object.
    2) Make the decision.
    3) Restore the omitted word(s).

Examples: Select either: I, me or myself

Ali and (??) prepare the document.
Please send the document to Ali and (??).
I will bring the required documentation for Ali and (??).

Answers:

Ali and (??) prepare the document.
Step 1\2: I prepare the document.
Step 3: Ali and I prepare the document.

Please send the document to Ali and (??).
Step 1\2: Please send the document to me.
Step 3: Please send the document to Ali and me.

I will bring the required documentation for Ali and (??).
Step 1\2: I will bring the required documentation for myself.
Step 3: I will bring the required documentation for Ali and myself.

PS:
Myself is used for an action done by the speaker and involves the speaker .
