Final Button Code

[skimask]

Do my momentary NO switches need to pull the inputs low?

Well, without a schematic, makes it a bit hard to tell...
But, if your switches are connected to +5v when pressed and open when not pressed, what voltage is present at the PIC's pin?
If it floats, the yes, you could probably use a pulldown.
OR...since you are using PortB, you might be able to use the in-chip weak pull ups and change the code to watch for a switch going low...
