Yes I studied the red heifer many years ago. It is an absolute requirement for the reopening of a rebuilt temple. It is needed for the purification rite.
A caution however about the site for the heifer's sacrifice and the location of the Temple. For 25 years I have studied where the Temple was. I am now convinced it was in the old city. South of the wall on what is now barren land. I believe the entire temple mount was the Roman Antonia Fortress.
Also, God's Word is 100%. It states that not one stone will be left standing of the Old Temple. Therefore the wailing wall cannot be connected with the old temple.
These are exciting times to say the least. Remember God's Word… I will bless those who bless thee, and curse those that curse thee. It is wise to take care of the Jewish people. This is a promise that is not dependent upon the moral state of the blesser so to speak. So our fallen and corrupt status will not stop the blessing if we help the Jews.
