1. I have just not noticed that the temperature gauge has gone back to normal after I had the engine washed...How hot should the coolant tank be even when the car is not overheating?

First verify that all your gauges are actually working. If they are, then I think you have no worries at all. I have only ever come across two cases where engine was overheating (coolant wa actually boiling) yet temperature gauge was normal. I'm told that can happen in case coolant level is insufficient (investigate for leakage, if any). In both cases, the fellows ended up having to replace cylinder heads (one had some very fine hairline cracks, the other had some obvious ones).
In the same breath, you may wanna avoid this idea of car wash guys literally washing your engine with that pressurized water thingie. Water can easily get into some electrical connections and stall your engine.
If engine has been running for a while, e.g on a long journey and you notice coolant is insufficient, let it air-cool on it's own (usually about 8hrs) before adding cold coolant/water.
That said, pay a visit to your mechanic just to be sure. All the best pal.
