Um yes, you made the correct play. there is only one case in which it is possibly correct to fold aces preflop, as discussed by sklansky in TPFAP. if you are in a huge expensive tournament, and you are in fourth/last place, and the top three people all have the same amount of chips, and they all push preflop, so that by folding you are gaurunteed second place, which must be a HUGE difference from fourth or even third place, ONLY THEN do you fold aces preflop. even then i don't think i would have the discipline to do it.
for all intents and purposes NEVER fold aces preflop. never. never ever.
you want to get as much money in there as you think possible preflop. going all in generally may not be the best move at this point because chances are you will not be called. if you think you can get called, awesome, and the more people you are called for, the better.
your initial raise was great, since there were already so many people in the pot. with aces, yes you want alot of money in the pot, but you don't want alot of people seeing the flop, so that was probably a good sized raise. and of course going all in was the correct move.
