1. Building. You are, in effect, erecting a minature tent. This is completely forbidden.
2. Carrying. It's forbidden to carry in a public space.
It's possible to make certain types of public spaces "private", and technically, one could open the umbrella either ahead of time or, according to some opinions, under another roof, so in those cases, it might be permissible to carry an open umbrella. However - that's pretty intricate and people seeing this might think was permissible to open an umbrella outside on Shabbat, so I've only heard of one rabbi ruling that way.
As for washing dishes - well. Scrubbing isn't really permitted. Squeezing sponges. Ashkenazim can't use solid soap. There's the hot water issue. But since it is possible to use cold water (or hot water in certain circumstances), liquid dishsoap, and things other than sponges, and people (us, increasingly) are bothered by letting dishes sit overnight, at least visibly, plus we do need to make the kitchen dairy for breakfast - washing dishes is permitted in those cases.
Many people will store dirty dishes in their dishwasher until Shabbat is over. There is no reason why not, so long as they don't run it, and it eliminates the piles of dirty dishes that might otherwise happen.
(And, seriously? If leaving dishes lying around unwashed would ruin someone's Shabbat, they are absolutely permitted to wash them in a halachically permitted fashion.)
