Dave, thanks for the advice!

I won't be planting any trees or shrubs, just a lot of small
plants--many of which will be rock-garden plants. Will this method
still work with them?

Like Dave said, wait the 2 weeks after you spray and then if you are doing a
rock garden, put down a weed barrier (ground cloth) that will still allow
for proper drainage. If you put the rocks on top of the dead grass you'll
have them start to sink very quickly. You can cut holes in the weed barrier
to dig holes so that the plants have contact with the soil below.

On a design note...

Small plants with big rocks, big plants with small rocks. Use at least 3
different sizes of rocks but don't mix too many colors. Home Depot sells
river rock (or egg rock) that has a nice mix of colors and sizes. Your local
garden center should be able to provide you with 3 large boulders (have them
deliver them!) Use them to create a grouping and surround them with smaller
rocks. Avoid the urge to put a pink flamingo in the middle.
