I am pretty sure Shanks wasn't a Yonko when he came to East Blue. Its quite possible he simply came to see where his captain was executed and Yasopp and others might have felt like meeting their families(those of his crew who belonged to East Blue), possible before they set off on their own journey to become a Yonko. But Shanks has definitely been to Raftel because only those who have been to Raftel or know its truth seem to be the ones not interested in it (Whitebeard, Buggy and Shanks ofcourse). It has been mentioned several times so far that the crew split AFTER they completed their journey across the Grand Line, and when Shanks met Luffy, he was already a notorious pirate but definitely not a Yonko.
