If you are running a clock, then you need to run all the time, or have a
pic that can take a second crystal for realtime clock at 32.768 KHz. Your
real power consumption, especially if you run the LEDs even occasionally,
is not going to be affected much by your choice of PIC.

How about 2 or 3 AA batteries? Then you will not need a regulator(save
current that way too).

Since you are a beginner, do it as simply as possible, which means no
multiplexing of pins. Get a 40 pin PIC like the 16F877(A) or 18F452.

Cheers,
