Not sure if kit and caboodle came before kit and caboodle but when I was a kid there was this thing called kit and caboodle where people had this box looking thing that they sold things out of. FAKE EDIT: Looking it up it looks like the phrase was around before the box I'm talking about. FAKE EDIT2: I can't find a picture of the Kit and Caboodle I was talking about. Seems like it was whatnot's and things. From the 1980's so my memory is not so fresh.
Saying you got the whole kit and caboodle means you got all of it and then some or just all of it. Whatever it is.
I wouldn't say "hook line and sinker" as this refers to fishing. The fish swallowed the hook, the line and the sinker. Meaning they suckered you into buying it or sold you into buying something. Or she was attractive enough to make you fall for her hook line and sinker. Along those lines.
