Don't make driving the manuals so complicated. No, as you decelerate, you can come almost to a full stop in 6th gear, and put it in first gear as you approach full stop (or stop first with the clutch pedal depressed and put it back into first gear when you start)..... You don't have to do anything. However, if you are going 100mph, and you decide to down shift into 1st gear, it's not going to like it. Sounds obvious, and in fact, you wouldn't even try it....
WHen I drive around town, to keep mileage up, I shift from first to third, then often fifth, and go down fourth to second.... just to not have to shift as often. The wide torque band on the car allows it to pick up well and easily from 2nd, 3rd and 4th at very low speeds....
If you're not an expert with manuals, but you know what a clutch is at least , then you'll have no problems. It's just that as you get used to it, it keeps getting funner and better.
