Well, for low power consuption, you might want to try some of the new
nanowatt PICs.  I think the 16F87 and the 18F1320 both have this.

To run 6 to 12 LEDS, you will need 6 to 12 IO pins.  Also, you will
probably want a few more inputs and outputs for buttons, or jumpers. 
Most of the PICs with more than 18 pins should cover this.

As for using jumpers for configuration, You would need some sort of
system to connect the pin to either ground or 5V, depending on the
jumper status.  I'm not sure if the pin reads high or low when just
disconnected.

I think nearly all of the PICs should cover all these requirements,
except the tiny 8 pin devices, and probably not the 18 pins (unless
you use strobing).
