So which range is Mt Shasta in?

It's in the Cascades, near the southern edge. Mt. Lassen is usually included among the Cascade volcanoes also, though looking at the map it seems a bit south of where the Cascades divide to make the Sierra Nevada (inland) and the Coast Range to the west, as the Central Valley (of California) lies between. AFAIK the other Sierra Nevada peaks include no recently active volcanoes.

Not nearly so old as the Appalachians.  They're barely even mountains anymore.

 

Side note: I have, somewhere, a picture of myself at the top of a 'mountain' pass in West Virginia, with the elevation clearly identified.  It's about 200 feet (60 m) lower than the elevation of my home town on the plains of Colorado.

Snoqualmie Pass (Interstate 90's crossing over the Cascades) is also low ... a bit less than 3000 feet, IIRC. There are passes on the shoulders of Mt Rainier that are not that much higher than that, though Rainier's peak is just over 4000 meters (14,400 feet).

 

It's all a big collection of accreted terranes, with massive volcanic towers built on magma pipes piercing through every few dozen km.
