You really should reverse the order of thinking here (see next point). While 
being able to think about values of components you have already made 
allowance for could come later, you may find that you need a different size 
footprint on the PCB if you change capacitor value - especially for 
electrolytic capacitors.

>I don't know what "power decoupling" is.

<VBG> this is why I say you need to think about what goes on the PCB before 
you make it.

You will require capacitors across the power supply to make the circuit run 
reliably, especially when the battery gets near the end of its life. 
Typically you will require a 47nF or 100nF ceramic chip capacitor across the 
VDD and VSS pins of the PIC - or at least as close as you can reasonably get 
it. It will probably also require some amount of 'bulk filtering' in the 
form of an electrolytic capacitor (most people prefer a tantalum capacitor 
for this) around 10 to 22uF, somewhere across the 5V supply.
