DSG and mechanical sympathy

I've just taken possession of my second automatic transmission car, and the second DSG. The first was a Jetta and now a Tiguan. Although I knew that the DSG used two clutches, I had mistakenly thought it still used a torque converter for the initial movement.

Now I know it uses the 'odd gear clutch' for moving off from standstill or hill starts etc, I'm (possibly unnecessarily) now worried about clutch wear. When driving a manual transmission I was careful to avoid clutch wear whenever I could, not fully hitting the accelerator until the clutch was up, not creeping by riding the clutch etc. Having now read a few guides about the DSG I still have a couple of questions on aspects I'd like to understand better.

One guide said not to 'ride the brake' when creeping in slow moving traffic. My question would be, at what point (revs, speed) does the clutch fully engage in first gear? If I am in slow moving traffic and I take my foot off the brake and creep at the speed the car naturally moves without pressing either the brake or accelerator, is the clutch fully engaged, or is it still slipping?

If I want to make a rapid get away from a standing start, is it possible to do the same thing I would in a manual where I get the clutch engaged as quickly as possible before really flooring it?

I am likely to be taking this car off road, and have read a lot about overheating clutches. It takes me to my first question of at what speed the clutch is actually fully engaged. Most of my off-roading would be at speeds above that at which the car creeps with no pedals being touched.

Even if the DSG is robust enough to not worry about this I always prefer to not increase wear if I can avoid it, so just want to understand it better so I can make my own choices.
