What is a good build of bukkit which allows the connection of 1.7.2-1.7.9 clients but does not yet use UUID's? If someone could point this out to me it would be nice, thanks in advance!
You can't have a version which works on both 1.7.9 and 1.7.2. Choose one of the following: #3084 1.7.9-R0.1 Beta Build #3020 1.7.2-R0.3 Beta Build
Yes, but plugins that don't support UUIDs will continue to work. Note that there are plugins which must be updated to 1.7.9 to work. My experience/advice with 1.7.9 is here: http://forums.bukkit.org/threads/wh...s-for-upgrading-to-1-7-9.265309/#post-2469675
