The "stretched-out" clouds are cirri, high-altitude bits of supercooled water that suddenly freezes and gets blown with the winds for some length of time before the crystals evaporate. They're usually to be found at a warm front, which gets pushed up by the colder air underneath.
When the cirri are large and numerous enough, they metamorphose into a thin veil of altostratus, an even sheet of clouds, that gradually lowers and thickens. This is a precursor of rain.
Winds in different altitudes are different, so yes, they're being blown away from you, regardless of the apparently lesser winds at the surface.
The small puffs of cumuli humilis are bubbles of air that've been heated at the warm ground and jump up in small bursts (think bubbles in a boiling pot). They're without much significance for the weather, although if the ground heats up and the air stays humid, they might be lifted higher up than they manage here and form the larger cumulonimbi, pillars of rainclouds.
