Tickety-Boo

Tickety-Boo may be related to a traditional Rosh Hashanah greeting Tikatevu (may you be inscribed).
If you are written in "The Book of Life" then all is well.

That strikes me as quite a stretch - do you have a source?

Let's address the 800-pound behemoth in the room: as a hypothesis, it doesn't strike me so much as a stretch, but I would be interested in a kosher source. To do otherwise would take a lot of chutzbah.
Interestingly, one reference I consulted defines tickety-boo as copacetic. While the etymology of copacetic is officially "orig. unk." (homage to Grant) according to most sources, one of the popular etymology theories is that it comes from the Hebrew (via Yiddish?) (ha)kol b'seder.
But don't mind me: such verbal tohubohu can be a bit much. Can I get a hallelujah?
