My text advice is never text more frequently than the girl, and never text longer texts than her.
This.
Also I agree with what Wolf said. If you don't really want to be texting all the time, then don't. But do realize that you may loose more girls that way. Relationships, and dating is all about momentum. That is why if you push for a date within a few days of getting her number, you will have a much higher sucess rate than if you try to set it up 2 weeks later. After 2 weeks, you have lost momentum and she can't really remember how awesome you were and why she gave you her number.
Texting helps keep momentum up because you are in her mind as a romantic and sexual possibility. So the choice and the tradeoff is yours. Feel free to text less, but it will depend on how much the girl likes you as to how that decision helps or hinders you.
