PLL is a step most common in layer by layer methods in which you permute your last layer pieces thereby solving them if they are already oriented. There aren't any edges to orient on a 2x2, allowing 2x2 PLL's to be shorter and less abundant than 3x3 PLL's. PLL is ridiculously easy for 2x2 because there are only 2 of them.
Alg Count - 2
PBL is a step used in the Ortega method for 2x2 in which you permute the corners in both layers of the cube. This might sound complicated or alg intensive but it is only 5 short algs - 2 of which are just the standard 2x2 PLL's.
Alg Count - 5
(3 minus the 2 PLL cases)
