Excel 2007 : conditional formatting a cell by its neighbor

[ben_says]

ben_____102.21
bob_____104.31
borris____120.12
jeff______130.212
jane_____118.121
doris_____109.42

so easily we can conditional format the right side column for the top 34 %
so the top two biggest numbers become bold.

however, i want the names of the people to become bold off the values
which are flagged in top ____ % via conditional formatting.

all other posts and writups on conditional formatting i have found use a simple,
well " set the cell =$b1>0 or b1 <50." i don't have a simple greater than equal to,
im using the top [or] bottom %.

any ideas.

thanks for your time.
