Unused IC inputs

[patchell]

    Unused outputs are easy...leave them unconnected.

    Unused inputs....depends on what it is.  The 4049, the inputs need to be
tied to one supply rail or the other.  The TL072, I have left input pins
floating, but you probably should tie them to ground just to be safe.  Most
important thing is that both pins be tied to the same voltage.
