An umbrella is an umbrella. They all work the same way. You may want to get an umbrella that has a design that you like. Even a basic plain umbrella would work great for keeping the rain off of your head.
No. Sunburn would be an example of absorbed energy.
Yes, you can get so many different types of umbrellas. I would start by look at the place you got your patio set.
I would say YES
The cost of umbrella parts depends on what type of umbrella you own. If you bought a fairly cheap umbrella, well, obviously the replacement parts would be fairly cheap too. If your umbrella was good quality and very expensive, the parts would be expensive as well.
There is currently a four-piece patio set available at Target. It comes complete with an umbrella and a table. The going price right now is $199, as there is a sale.
ALL OF THEM!!!!!!!!!!!!!!!
A professional would be best in advising you of that. Perhaps go to the place where you first purchased the patio table to see which umbrella would be most suitable. If all else fails, try looking on eBay, or online market. There is a large range, just browse through and see if something catches your eye or measurements.

I would recommend the Tahiti stands and also the Tahiti umbrella. This patio furniture can be found at Sears. The Tahiti stands only cost $99.97. The Dakota umbrella costs a little more, but I would also recommend the Dakota umbrella.
The best material for an outdoor umbrella would definitely be canvas. Be sure to provide at least 2 feet of extra space on all sides of the area you want to be covered by the umbrella. The most cost effective and longest lasting brand of umbrella would be Sunbrella.
I understand that auto shops carry spray paint for vinyl.
