Phaedon, This won't address all your questions, but will get you headed in the right path.
At the system command line: sage -clone finance-test will make a copy of the a tree parallel to devel/sage-main, and the symbolic link at the same level named devel/sage will point to the new tree devel/sage-finance-test. You can experiment safely in this sandbox and for free you get a Mercurial repository to track your changes. In the developer's guide read about the hg_sage commands to use a simplified interface to the repository. If you edit files under devel/sage-finance-test, then at the system command line sage -b will rebuild just the edited files. If you now run sage, at startup it will report in the first few lines which sandbox you are playing in. sage -br <name> will switch between sandboxes. sage -advanced will list a few of these commands. I'm new to all this, so others can add, correct or clarify. Someday, I might write-up some of this (and more) for fellow rookies.
