I'd recommend getting a PIC with an internal oscillator... This'll save you=
 a=20
few external components and a few I/O lines.. depending on what you intend =
to=20
store, you may need to get an external EEPROM.. if so, you'd need to get a=
=20
PIC with either I2C or SPI capability to access the EEPROM, or you'll have =
to=20
bit-bang it (which I wouldn't recommend for a starter project).. So, which=
=20
pic you pick, depends entirely on how much RAM/EEPROM/FLASH you'll need..

A 18pin PIC should do that easily.. you'll need between 4 to 8 pins for the=
=20
4x4 keypad and 6 to 7 pins for the 16x2 LCD... for examples on doing this,=
=20
you can check out the I/O section of www.piclist.com.. that leaves you with=
 a=20
few extra pins you could use for lighting up LEDs or buzzing or something..
