You only need to select revisions if you don't want all un merged revisions to be merged. This is a feature of the merge tracking added to svn in 1.5+.

It doesn't really matter when you do the branch. But, I usually start it ahead of time. You will gain aloof info by reading the free svn book http://svnbook.red-bean.com/nightly/en/ especially chapter 4 on branching and merging with particular focus on the branching strategies section.
