what style were you going for? just a pale ale?
in the future, if you're really wanting to get some flavor and aroma out of those hops, don't do that 30 min addition. (oh, also, when people talk about hop additions in the homebrewing world, they will give the time that the addition of hops will be in the boil) I would do the 0 min addition like you did (that one is also called a flameout addition), and take that 30 min one to a 5 min one. Or just put them all in at flameout.
As far as the dry hopping goes, you wanna wait until the fermentation activity has slowed down. Some people like to wait until it's absolutely finished and there's been a significant amount of off-gassing, because they feel they lose some aroma to the off-gassing. I personally don't think it makes too much of a difference, and love to multi-task, so I wait until the fermentation activity has began to ramp down, and krausen has dropped. That's usually around day 5-7. Just throw all the hops in at one time. Leave them in there for another 5-7 days or so. Then cold crash for a few days, then package as normal. If you're not going to cold crash, then I would wait until you start seeing that the yeast is dropping clear. If your fermentation isn't done in two weeks, then you've done something wrong, or you're using one of the very few "complicated" yeasts. For most yeast strains, fermentation will be complete by day 9-10. Here's a great experiment that shows the difference between one dose of dry hops vs. multiple:
