Donnie mentioned Photoshop brushes when he was here.
Photoshop does have default brushes. Some of the standard viewable default brushes are Spatter, Chalk, Star, etc. Make sure you click on the small black arrow next to the word Brushes to view all of the brush sets avilable.
Brush sets are usually located in the folder C:\Program Files\Adobe\Photoshop X.X\Presets\Brushes (where X.X is the program version). To make brush sets that you download load automatically, they must be in this folder. Otherwise, you can load them manually by selecting Brushes > Load Brushes…
