About the pre-glued patches advice - I don't use them myself, but in the context that the dude-in-distress had never patched a tube before and I was trying to get him home as easily as possible I thought pre-glued would be faster and easier.
With the normal type there is a possibility of using too much / not enough 'vulcanizing rubber cement' and the drying times are longer, and the tube can then get stuck to the tyre... but it rocks because you can use old inner tubes to patch newer ones if you are really cheap.
