You can use the "and" or omit the "and." I'm told it's mandatory in either the US or the UK, but I can't remember which, since I tend to use it.
Note that forty is spelled without the U. I don't know why, but it is.
As an American, I would read 01/08/2010 and January eighth, two thousand ten.
I expect everyone else will tell you August first, two thousand ten.
Some people will also say twenty-ten.
