Plant Sciences, Zoology & Evolution / What evolved first? Legs, or a sense of balance?

Another seemingly paradoxical occurrence in evolution.. Is a balance and/or motor system "randomly" developed first to assist the "random" generation of legs? or are legs "randomly" generated and a balance and/or motor system "randomly" developed afterward to use them? Or were they "randomly mutated" simultaneously in most cases? I know the answer is there.. I just need someone to point me in the right direction.
This also brings sexual organs to mind(perhaps this should be an entirely different thread) but how did sexual organs develop over time through random genetic mutations? they couldn't have been immediately beneficial to a species... so how is it that they evolved into such complex organs? A species must have already had a way to reproduce while in production of new sexual organs, right?
