First thing I'd say is, take a breath it will be fine. I don't see any reason you would lose the new sod unless you don't water it and there's no rain at all. Part of the reason so many of us enjoy the lawn is that it is a perpetual work of art that is always presenting new challenges. It takes some time and experimentation to learn how to respond to the different situations that come up. The best part is that short of letting weeds take over and ignoring the lawn altogether, it usually will bounce back. Remember, your lawn today is a result of what has happened to it over the last several months. I killed large chunks in my back yard with a large overdosing of some weed killer this spring and most of that has just about recovered now.
It's still a little early in the season. I too added some new sod last fall and put sand on it this spring. It's about 90-95% grown in. I have been putting fertilizer and extra nitrogen down every 3-4 weeks to speed up the growth over the sand. It's workong, but still have a little ways to go. There are spots where the sand got "messed up" and moved from where it should be, but I just put it back flat with a rake or even just my foot and once the grass grew over it, it was good and now the sand is "locked" in place.
So just address the problems as they come. I would just rake the sand back to where you want it, keep it watered and fertilized. Be sure to put down a good pre-emergent and address any weeds that come up with spot spraying. Just take it a step and a day at a time. All the little things you do will add up over time and you'll have that golf course lawn you want in no time.
