I must say though that this is a fantastic powerful car and is a pleasure to drive
Welcome to the wonderful world of Renault ownership
The dead sensor could be one of two things: Either the sensor is faulty, or the computer has lost synch with it. In either case, it's a dealer or specialist job, as the diagnostic computer is required. The only difference will be whether you need to pay them 25-ish quid for a new sensor. The other tyre may be losing pressure, or it may just be on the threshold of triggering the warning. Cold tyres are naturally at lower pressures than ones that have warmed up, and the recent cold weather means the temperature and pressure differentials are greater than usual.
The number plate lamp is probably a loose bulb or a dirty contact. Dismantle the thing, make sure the contacts are clean and clamp the bulb tightly, and re-assemble. If that doesn't fix it, then I'm guessing it's a loose wire somewhere. A momentary loss of contact may be enough to trigger the warning system.
There's an extra button on the driver's seat control panel that stores the current seat and mirror position. You have to press and hold it for a few seconds, after which, it should beep. As you have the voice synth, the car might give you a spoken message instead. The seat and mirror positions are linked to the card, so if you have more than one card, you can give the other one to someone else and have it remember the appropriate positions for them. The car will configure itself whichever card unlocks it. On starting, the system should also remember the driver's climate control temperature and whether the stereo was playing CD or radio when that card was last used.
There's an article on repairing the light in the stop/start button on here somewhere. There's a link to it in the Laguna FAQ.
