One way of finding (and removing) duplicate entries is to sort the column and put a simple formulate in a temporary column next to that column; for example - if column A has duplicates, insert a column (B) and starting in B2 put if(A2=A1,"DUP",""). Select B2 and scroll down to the bottom of your spreadsheet. Press <ctrl>-D to extend the formula in B2. Wherever there is a duplicate you'll see "DUP" in column B. If you want to remove the duplicates copy column B and Edit / Paste Special... with "values" selected (to wipe out the formula). You can then sort the spreadsheet on column B and remove rows with DUP in column B.
If you can't delete the duplicate rows and the order is important first include a column that captures the order - same trick except put row() in that column, copy / paste special the values and then you can re-sort after doing the above to have both the DUPs marked and the original order.
Hope that helps.
