A little more soil will probably help if you do have a lot of sand underneath. But, I'd also recommend not filling it to the top and leave room for a good 2" layer of mulch, such as grass clippings.
If you fill it to the top with soil, wind and rain can wash off your mulch.
Fresh grass clippings will add all the nutrients you need this year, but every year after I'd add a slow release organic fertilizer.
For now, I'd leave the plants in place and just add the mulch.
