the best place to go to get a really good sun umbrella is your local garden shop or if you live by the beach got to the beach shop and they should have some good selections for you to choose.

It's certainly possible ! I have a black t-shirt which has faded to a grey/brown colour on the outside - but is still jet-black on the inside !

You can get umbrella covers in any normal outdoor furniture store. It depends on the size of your umbrella. Check with the store where you got the umbrella .
It is not always cooler under an umbrella. Just as an umbrella can shelter you from rain it can also shelter you from the direct rays coming from the sun. When it does so it creates a shadow and the shadow is cooler than the full sun. However just as an umbrella will not shelter you from rain when it is not raining, an umbrella does not provide a shadow at night or on overcast days, so you will not be cooler under an umbrella then.
