As someone who was new to dslr photography this time last year and did as well as I could, (though I use Canon, here are my tips/tricks) (and this is probably WAY too late, but hey, there's always next year or other nighttime stuff!)
-WHERE you shoot is going to be the most important, pretty much everywhere in Frontierland is completely darkened, if you must shoot there, find a spot with a spotlight. Main St is better, but tricky because of all the mood lighting on the buildings, my personal favorite to shoot in is under the train station, or across the street from there, best spot was standing under the train station off to the right hand side near that garbage can, facing the parade as it came.
-Don't use flash, it'll wash the photos out and make them not look as nice.
-Bump up that ISO, but personally I find it adds way too much noise if you go above 3200
-Widen the aperture as wide as possible (lowest number) this is where the kit lens gets tricky, mine was okay, but once I got the 2.8 lens it was a million times better, it was a knockoff brand so I'm super excited to try with my actual canon lens that opens to 1.8!!
-Shoot in aperture priority can help too, this way you have less to worry about as the camera will do the shutter speed for you
-Aim for the WHITE light, and shoot, and shoot a LOT
-Dancing performers and floats will need potentially different settings, usually the floats are pretty well lit while the dancers need more light.
-The waltzers, and the cowboys are so hard to shoot thanks to them moving so fast and so much, ie, higher shutter speed there.
-We also found that the fur characters came out a lot clearer in shots than any of the face characters/dancers

I also use the adobe photoshop express app to edit my photos before I
instagram them (they are NOT edited with it on this post/flickr) it is AMAZING, my pictures, especially nighttime ones are WAY better after using it. I did try to find some pictures with my kit lens but I appear to have not liked them enough to put them on flickr. Lol. Happy haunting.
