Treeboy, you definitely should take a class.  A lot of the things you are asking about now will be super simple once you've taken a short class about it.
An alternate solution to what moss offers is to have a seperate shorter rope that you use to connect yourself to the tree before disconnecting the primary climbing line.
Good luck!
