Puzzle Time

I've decided to create a cryptic puzzle.  Below you will find the clues and below that is the grid in which they fit.  You will have to excuse it a little since it is create using Paint...but anyway.  Now the clever thing is that all the answers link to a particular year.  Once you've got the answers (or some of them) make a guess at the year.  I've hidden comments on my blog for the moment so you can send me the answers without others seeing them and I will give out the answers in roughly two weeks time.  Good luck and have fun.
