John,
to you, new member!
I also live in Sonoma County zone 9a and with my semps, there are some that shy away from the full sun for lots of hours. I have my semp bed in a place where it gets afternoon sun but I have to resort to shade cloth on top of the bed from 11:30 to 4:30PM so that they don't get fried. Also, last winter we did get temps that dipped to high 30's and low 40's and my semps colored nicely. I have some semps like the arachnoid types that are hairy, ciliated or fuzzy that aren't in the semp bed because they don't seem to do well there. Those seem to like the morning sun better.
Your echeverias should do fine as they don't need as much sun but in the winter, they need to be protected in some way. I chose not to overwinter them indoors as I believe in Tuff LOve and so I just pushed them against the house or under the eaves with frost cloth over them at nite.
