I'll 2nd DJ's advice -- great advice DJScribbles! All of these items are necessary. In a realtime system, the world is never kind. Odd things do happen and null pointers and failures do occur occasionally. As programmers, we like to program for perfect systems as it makes our jobs easier, but alas this isn't reality. By carefully taking each step, you'll likely find that things work much more reliably.
