You can just lay compost down on top of old mulch. The worms will work it into the soil for you.

Covering the old mulch with compost, then more mulch is perfect, laboring saving too.

Another addition that can help, sulfur, that will help loosen up that gumbo you garden in. Lightly and frequently thru the year is better than all at once.

Lastly, there is no such thing as too much compost, I am careful to keep it a foot or so from the stems/trunks of the plants. Plants 'breathe' there and you don't want to create a 'home' for pests.
