I'd go for a laser collimater if your just starting out with collimation, it's much much much easier than trying to figure out reflections. Plus you dont have to look down the eyepiece. They cost more but are much easier to use. BTW I have both.
You can collimate the secondary just looking down the tube. And for the primary mirror I use a small makeup mirror on a stick so I can see down the tube whilst standing at the back of the scope.
You dont actully need one though you can collimate with an out of focus star.
