How do you cover the effects? Like an imaginary overlay so you can have a muzzle flash positioned behind someone.

There are two basic ways:
First, if you film the elements of the scene separately, you can layer them in whatever order you want. So if you film a person on greenscreen, then you can put the muzzle flash layer below them on the timeline, and the person will cover the muzzle flash where they overlap.
Second, apply a mask to the muzzle flash, and draw it to match the shape of the person, so that part of the effect is removed. In most cases, this is the best option. For effects that last longer than a muzzle flash, you will often have to animate the mask to follow the shape of whatever object is blocking the effect.

Thanks! Would this work the same for an AlamDV2 plugin?

Yep, process will be exactly the same for stock footage, which is what the plug-ins are, as it would for a preset. Apply a mask to the layer you want to remove part of, or place the layer below whatever layers should be above it.
