Use the 16F628. It costs the same, has additional analog inputs and an
integrated oscilator. It also can be programmed at 5V with USB
programmers without power supply. They are even binary code compatible,
as long as you add two commands to switch the analog comparators off.
You get tons of information on http://www.microchip.com and on
http://www.piclist.org including sample programs. Also, the web is
*FULL* with PIC sample code for every event in life. Google is your friend.

The PIC16F628A is a better choice again*. (also consider the 16F648A
Currently it's less than half the price in 100 qty.
The 16F628 & 16F628A have twice the code space, three times the RAM,
and double the EEPROM. The PIC16F648A has a bit more RAM and double
again the code space and EEPROM. The 16F88 has the same code and
EEPROM as the F648A, 40% again more RAM and 10-bit ADC, still for less
than the 16F84A!
* Microchip still sells both types.
