Edición
After unwrap, you will likely need to arrange the UV maps, so that they can be used in texturing or painting. Your goals for editing are:
Stitch pieces (of UV maps) back together.
Minimize wasted space in the image.
Enlarge the faces where you want more detail.
Re-size/enlarge the faces that are stretched.
Shrink the faces that are too grainy and have too much detail.
With a minimum of dead space, the most pixels can be dedicated to giving the maximum detail and fineness to the UV texture. A UV face can be as small as a pixel (the little dots that make up an image) or as large as an entire image. You probably want to make major adjustments first, and then tweak the layout.

Blender offers several ways of mapping UVs. The simpler projection methods use formulas that map 3D space onto 2D space, by interpolating the position of points toward a point, axis or plane through a surface. The more advanced methods can be used with more complex models, and have more specific uses.
Pin & Unpin

P, Alt-P
You can pin UVs so they do not move between multiple unwrap operations. When Unwrapping a model it is sometimes useful to «Lock» certain UVs, so that parts of a UV layout stay the same shape, and/or in the same place. Pinning is done by selecting a UV, then selecting Pin from the UVs menu, or the shortcut P. You can Unpin a UV with the shortcut Alt-P.
Pinning is most effective when using the Unwrap method of UV mapping, for organic objects. An example is when you are modeling a symmetrical object using the Mirror Modifier. Some of the UVs on the mirror axis may be shared across the mirrored counterparts. You could pin the UVs that correspond to the midline, then align them on the X axis, and they will stay in that location.
Pinning also work great with the Live Unwrap tool. If you pin two or more UVs, with Live Unwrap on, dragging pinned UVs will interactively unwrap the model. This helps with fitting a UV island to a certain shape or region.
