Kitty wants human attention. He knows two ways to get it. One is to follow you around making friendly overtures. When that fails, it's to do something annoying. (Mine are the same way, and when they feel neglected but 'asking' for my attention doesn't work, they get up on counters where they are not allowed, or climb the bookshelves and pull books off onto the floor. Negative attention is better than none at all.)
You can limit this stuff. Give him attention and play at the same times every day, or in the same order (you might eat breakfast at a different time on the weekends, but if you play with him every day after breakfast, he'll figure out the pattern) or after giving a signal that says it's time to play or get pettted. (Best, really. Mine know it's playtime because I get out toys, even if we don't use them, and also quickly learned that if I put a blanket over my lap, they will get petted if they get on my lap while the blanket is there, so it makes them jump up. They are allowed on my lap at other times, too, and sometimes get petted or sometimes ignored or pushed away, but if I only petted them with the blanket there, they'd stay off me at other times, mostly.)
The time of day, routine order, or signal is a cue to the cat. Just ignore the behavior when it occurs without the cue. If you break down and respond to the behavior after it's been going on long enough to drive you nuts, you'll be training him to do that annoying stuff longer and harder, and training him to think (correctly) that he can cue
you into doing what he wants.
Eventually he's going to learn that your attention is in adequate supply and will be offered on a regular and predictable basis, and that all he needs to do is wait for your cue to get it.
This may take a while, because he learned things from his previous owners, and because he's probably acting anxious and OCDish because he is a cat and just experienced a major life-change. There's a homeopathic quack-seeming remedy you can buy in health-food stores called "Bach's Flower Essences RESCUE REMEDY" that works very well for mellowing out anxious cats. And me, as it happens. Put a couple of drops in his water if you want to try it.
