"your engine is now idling, which require gas"? When your engine is running it ALWAYS requires gas.

Rev match downshifting and brake.
For you guys who keep saying, "you don't use gas when...". If the engine is turning over, it is using gas period. Whether you're braking, in neutral, in gear, whatever. When the engine turns over, it is firing therefore using gas. The only time it doesn't use gas is when it's off.

There's something called the DFCO (deceleration fuel cut-off) that basically stops fuel delivery when the car is decelerating above a certain RPM (when in gear and not pressing the gas pedal of course)...
Here's a quick source of info:
http://en.wikipedia.org/wiki/Manual_transmission
Or use google to find other sources of info related to DFCO

Here's a more indepth explanation about it, especially the 2nd paragraph:

Hope everyone now understands that it does use less/no fuel when you decel in gear as opposed to going to neutral.

I personally like to downshift until i'm at around 5K or so, then sharply turn left (or right depending on the street), then hit the hand break, this swings the momentum forward, i then let go of the break and stab the gas again (its important to keep high RPM. I then "drift" in a circule around the car next to me, I usually end up with a phone number. Like my friend Dom used to say, winning is winning...

I usually coast in gear then put it in neutral and use the brakes... I usually only downshift to accellerate... or if I'm heading into a turn that i plan to accellerate out of.

If I'm coming to a short stop, I use the brakes with the clutch out. When I'm on a long stretch that comes up to a light I'll progressively drop gears until I'm in 3rd and then just brake in. Just using a transmission doesn't generate improper wear.
Generally when city driving however I stay in a gear lower than where I'd like to be so I can react better should something unexpected happen.

Depends on what I am doing.
usually when I just come to a stop light ,it is neutral and brakes.
if I'm going around a lot of turns and I feel like doing some 'spirited' driving, I usually keep the car in the appropriate gear allowing it to accellerate and decelerate accordingly around the turns.
In more 'emergency' situations, or I feel the desire for some additional braking power, I will sometimes use maybe 4th and 3rd to help slow the car down, but usually nothing lower than that.

I have been driving cars for over 50 years now, everything from 3 on the tree, to automatics and my current 6 speed manual with a few 4 speeds and big v-8s thrown in. I have always down shifted when approaching a stop and I have never worn out a clutch or broke a transmission. You just have to be aware of your speed and not try to jam the transmission into an inappropriate gear. With the more modern transmissions and syncro-mesh there is no need for rev matching either as you can snick the transmission into lower gears quite smoothly and with no gear grinding. Just as I roll to a stop I'm selecting first gear and I'm good to go and I have just barely touched the brakes and have not abused the clutch or transmission.
Oh yeah.... I downshift my motorcycle too to decelerate.
