I got this plant from a group of four in a pot/bog of death I bought at a BBS. It's so terribly etiolated. What should I do with the poor dear? Chop it's head off? Leave it be until Spring?
Chop and slowly introduce both to increasing sun until full or nearly so. Do it now.
As you've no doubt guess, you don't want to handle the leaves. The marks aren't anything but disfiguring, and the plant will, of course, grow out of the handling marks by getting rid of the leaves. Farinaceous leaves can be the bane of one's existence. Try smudging up a mature Echeveria lilicina (this was nearly a foot wide) and you'll really hear the shouting.....
I was going to say something similar to what Cactus said, but I'd say he knows a heck of a lot better than I do how best to handle this.
My advice was going to be to put the whole thing in full sun and allow it to recover, as well as plucking a few of those leaves off to let them root and start a few new plants.
But, as I said, you'd do far better to heed Cactus' advice. I'm still fairly green to all this, and just going by my own experience. I have a few Eches, Pachys and Graptos that have etoiled on me, and that's essentially how I handled them. They seem to be doing ok - the abrupt reintroduction of full sun hasn't hurt them - but what I've ended up with is a long, nearly-bare stem capped with a "hey, that looks better" rosette on the end - probably not what you're looking for. For example:
(This one actually began to curl over on itself when I put it back in full sun, so when it bowed low enough to the soil top and I noticed a little root reaching for earth, I tied it down with that red string; I'm hoping it'll take root from the rosette and grow from there.)
You may take these all as fine examples of, "Yikes! What the heck did you do to those poor things?? Give 'em some light, for Pete's sake!"
~ off now to look up the word "farinaceous"... ~
Ha! I'm off to look up etiolation.
