ExcelBanter - Top 25 List of Times

I have a spreadsheet with the times run by individuals over a 3 year span.
I've been able to create a Top 25 list out of those times, but am having
trouble with some other aspects (only part of the table is shown, so
hopefully it will be enough). I want to:
a) have Excel give me the name of the runner next to the Top 25 time
b) create a Top 25 list without any repeat runners and give the name with
the time
c) create a Top 10 list for indvidual classes (i.e. Freshman, Sophomore,
Junior, Senior)
