Progress looks fine based on your description.

The one thing I would do is tap into any “inside jokes” or anything that you were able to develop in conversing with her (for example, a funny aspect of a story she told) and incorporate that into the messaging. This elicits a reaction from her (“OMG HAHA”) that will break any strange tension, if there was any. Little inside jokes/topics are very intimate and engaging. So instead of “nerd”, try something like “Hey bath salts fiend, lets go rock climbing next weekend.” (IF you had talked about bath salts, etc.) Just incorporate a funny episode, words, characters into your interaction with her and it will take you a long way.

You already know this: the more she laughs and has fun with you, the more she will want to hang out and thus, more attraction. Most importantly, have fun, she’ll notice.

Thanks man, good advice. I should add, her being a nerd was actually something we talked about. I kind of DQed her on it though (basically teased her for not being nerdy enough after she claimed to be one).

Actually you do give me an idea, one of the things she talked about was a horible date she had with a guy that reminded her of the dudes on jersey shore. How about something like "hey nerd, just drove past a tanning salon and a hat store (part of the story she will laugh) and it made me think of you. Ever been rock climbing?" (Kudos on the awesome second date idea btw).
