What does 生命诚可贵 爱情价更高 若为自由故 二者皆可抛 mean? 生命诚可贵 爱情价更高 若为自由故 二者皆可抛


I think it means "life is expensive, but love is even more so.  However, both are not as good as freedom."
It's a little different from yours at the latter half of the sentence:


  Life is dear, love is dearer. Both can be given up for freedom.


Reference:

This is the poem written in 1847 by the Hungarian poet Sándor Petőfi. Here is the original:


  Szabadság, szerelem!
  E kettő kell nekem.
  Szerelmemért föláldozom
  Az életet, Szabadságért föláldozom Szerelmemet.


Here's the translation by 殷夫 in 1929, which adopted Chinese classic five-character poem style, but not totally faithful to the original text:


  生命诚可贵，
  爱情价更高。
  若为自由故，
  二者皆可抛。  


Another translation by 孙用 in 1957:


  自由，爱情！
  我要的就是这两样。
  为了爱情，
  我牺牲我的生命；
  为了自由，
  我又将爱情牺牲。  


Another translation by 兴万生 in 1991:


  自由与爱情！
  我都为之倾心。
  为了爱情，
  我宁愿牺牲生命，
  为了自由，
  我宁愿牺牲爱情。  


In English:


  Liberty and love
  These two I must have
  For love, I will sacrifice my life
  For liberty, I will sacrifice my love
