800 DP is better. DP, imo, is the best option by far, and you should choose it over everything. And since Nyarly's highest possible HP is 15655 (courtesy of hungryapp), 20% increase 3131) would be better in the higher level, but 2000 HP would be better in lower level.

My suggestion with Nyarly is to go with 2000 HP, since you're going to replace her in the future anyway. Of course, if you think you'll be using her for a long time, then 20% increase would be a superior choice.
