Welcome to TCS! Cats are amazing animals - and I'm so glad you found TCS to help you figure them out.
The most important thing to remember is that cats are great at hiding pain and problems - so whenever you notice a change in behavior, or whenever you observe "strange" behavior, it is ALWAYS best to be safe rather than sorry and take your kitty to the vet. Most behavior problems are actually health problems. For instance, peeing outside of the box is most often because of a urinary tract infection, or bladder infection. The licking, as hissy pointed out, could very likely be due to a skin problem. Many cats have very sensitive skin, or allergies, and there are quite a few foods available on the market to meet these needs.
Obsessive licking can be a sign of stress, but you have to rule out medical problems first.
Also, the blanket sucking is sometimes a genetic thing with cats, and may have nothing to do with being taken from mom cat too early. Were the blankets wool? There is, actually, a "wool sucking gene" in some cats! We rescued a stray that loved to knead, would drool like a maniac when being petted, and sucked on blankets and wool. If they do not ingest the wool, the sucking is not a problem - other than needing to wash a few things more frequently.
But because she exhibits this behavior, and if it turns out there is no medical reason for her grooming habits, then perhaps it is related to the stress this kitty for some reason is experiencing. Then please search on "obsessive licking" in this forum, and you'll find lots of suggestions and potential solutions.
We have a kitty that began stressing out - we moved into a new home, brought home a new kitty after a few months - and she already had some issues with an existing cat here that is a bit aggressive at times. We seem to have helped her through her stress by using a combination of play therapy, flower essences, and what I call "love" therapy - just spending a lot of time with her (she likes to sit on my lap and be petted) alone, with quiet music, petting her and reassuring her that she's OK. Any time I see her grooming "normally," I let her be. Whenever I notice her doing it obsessively, I approach her slowly, talking very reassuringly, and interrupt her gently - and she licks my fingers wildy for a minute and then calms down as I begin to pet her. She has no more bald spots, and this seems to be working.
