I can't answer your questions about pairing with daystar, though someone else might be able to.
I just put this set on my truck Sunday. I'm still working on adjusting the height. I gained 3" in the rear and 4" in the front. I'm bringing the front down today to match and then letting it settle over a couple hundred miles before aligning it.
You can look at my build thread to see more info. My lift is on the last page, I believe.
