Your yarn will stay in the back if you are just doing the knit stitch (which will create stockinette stitch).
You can pull the first two stitches on each new needle VERY tightly to help get rid of some of the ladders.
You can also mark the beginning of the round with a stitch marker and then knit several stitches from the next DPN on to the current DPN - so you finish one needle and then knit one or two stitches from the next needle on to the needle you just finished then start on the next DPN. The stiches will move around so the BOR marker wil not be in the same place, but you know where it is.
Washing also helps take ladders out.
