8.05 merely contains some fixes all of which have been done in the FML version of 8.04. Nothing to worry about.
You're not supposed to be downloading other versions of MCP, it might break FML/Forge and is totally unsupported.
Run this:
http://files.minecraftforge.net/minecraftforge/minecraftforge-installer-1.6.2-9.10.0.846.jar
Select 'install server', select an empty folder, then ftp the folder it spits out into your server.
