<p dir="auto">Yes, taking them offline won't make a difference. What does make a difference is to clear the Email Address(es) field in the accounts for which you don't want to use their SMTP.</p>
<p dir="auto">The duplication of sent messages is caused by Gmail insisting on making a copy of anything sent via their SMTP in the corresponding IMAP sent messages folder. This is done for efficiency reasons, but it's non-standard behaviour and it can easily confuse the email client (well, confuse the implementer of an <em>IMAP</em> email client).</p>
