Hi Matt
I assume the DS 10 is a 10" Newtonian? And it is f4.5?
Assuming that is correct, yes it will need reasonably good collimation to get the best possible views. Please remember that you are always better off getting pretty good collimation then taking your scope outside and enjoying it than trying for perfect collimation and wasting valuable observing time.
I have used this guide here
http://www.astro-baby.com/collimatio...on%20guide.htm to collimate my scope and it is really quite simple. Print it out and read while doing. The critical thing to remember is that the laser is ONLY for the final tweak. There are an infinite number of versions of misaligned optics that a laser will give good readings to. Try and get a cheshire/sight tube combo such as this

Also, at f4.5 a bit of coma is almost inevitable and collimation will not fix it, it is inherent in fast newtonians. You could get a coma corrector if it really bothers you, but in my opinion you are better of getting good quality wide FOV eyepieces.
