First thought on a6 is he wanted to prevent n-b5 although that is far from deadly.

h6- at first I thought he wanted to bring out his knight witout allowing a pin.  But, then he moved the bishop so that wasn't the idea.  I think it was probably because he wasn't very good and didn't know what to do. 

I agree with erikido23... a6 was to prevent any of your pieces from placing itself on b5, which, if it wasn't really something he or she should be worrying about so early in the game, might end up helping him (or her)...

h6, however, seems pointless... It is an utter waste of time, specially since the bishop needed to go to e7 anyway,

he was ok his rating was around 1400

some people are fancy and like to play a6 and h6 in all their games.

how is that fancy?

I think that's the most likely explanation because he seems to be quite a defensive player.

what about Qc8?

The weirdest thing is why he resigned. He was ahead.

 not quite sure that is true:

I think there's another explanation for the a6 h6 moves. My Dad taught me chess when I was a kid & back in the day those two pawns would be moved forward in the process of positioning before undertaking any attack. 

Maybe your opponent is old school like my dad... 

The guy was simply trying to keep pieces (most likely bishops
) off g5 and b5.  

Some weaker players fail to realise that these pins are only sometimes dangerous and so prevent them in every case and at every opportunity.

Not a bad game though Vincent...although your opponent played somewhat like a beginner.
