1) decade. I see sentences like this in the media all the time:

"Slightly less than two decades ago, she was the happy mother of four..."

The writer is a journalist and presumably has the facts. If it was 19 years, say so. Better yet, say "In 2001, she was the happy mother..."

2) Most where almost should be used. "Most everybody enjoys ice cream." arrgh!   

3) Alright instead of all right. I guess alright was born of its visual similarity to already, but already isn't the same as all ready.
