Turn on, make sure you have oil pressue, then go. No need to sit and warm up. Just make sure you drive 'normally' till the car has warmed up completly (10mins or so)
yeh wastes petrol on cold starts,
start and go and normally i keep my revs under 2-2.5 for say the first 10mins sometimes i give a little more say 3.
Once warm im up to 6-7k
agree. just dont go making yoru engine work hard form the get go.
i personally let it idle for 30sec-1minute, then drive gently (2-3k revs) till engine has warmed up then if i need to push it a little i do.
just personal preference.

Extended idleing is bad for fuel consumption. 30sec-1min for me on cold mornings as my car doesn't like to idle for the first minute or so if I take off earlier. IACV is clean and no vacuum leaks either
I read somewhere that letting it just sit there doesnt warm up your gearbox, so it's better to drive it gently. Is this true?
Yes, though keep in mind that the gearbox isn't as sensitive as the engine to being properly warmed up.
This isn't to suggest that it's OK to 'fang it' as soon as the temp guage nears / reaches 'normal'. It's not a good idea to drive the car hard (or more than fairly gently) as soon as the coolant is up to temp because the oil temp lags behind coolant temp. It's best to give it a few more minutes to make sure everything is thoroughly warmed up. Cold oil doesn't lubricate as well as warmed up oil.
It's not a good idea to leave the engine idling for any extended period because oil spray onto the bore walls ('flinging' off the crank from the big end bearings) at idle speeds is not great, and the pistons may be running with less oil than is ideal. This is especially the case when the oil is cold and thus thicker than at operating temperature...
