@ Eeveeskitty:  I would say attack, speed, hp, and either defense or special defense would be the 4 most important stats for a normal dd dragonite.  Defense over special defense if you want a higher likelihood of surviving ice shards, special defense over defense if you have a habit of switching dragonite into grass, fire and water moves.
@gabriel:  You can use the formes on link battles though, so they're not entirely useless.
@Vinceisg0d:  They are both excellent parents, though the murkrow would need to be bred with a ditto if you want a good chance at a better nature.
Yes, egg moves are inherited if the father knows it, the mother doesn't matter for egg moves.
You should value hp over special defense for your togekiss as its special defense stat is naturally higher than its hp stat (also hp applies to physical defenses too...).  However, hp is harder to inherit IIRC...
My advice is to get the triple flawless female, then soft reset breed.  This gives you a much better chance of getting something usable as you won't have to deal with hustle or wrong nature babies.  The 1/468 statistic is intimidating, but you don't have to get quintuple flawless.
