On (1), I use command-line SVN so I have no advice on that (though AFAIR there's nothing Tortoise-like for OS X). The things I found with a Google search are the same things you will have found and I have no experience with them.
But on (2), the happy news is that this Unicode navigator is built into the OS and is one of my favorite ways to browse Unicode. In System Preferences->Language & Text->Input Sources, simply check two boxes: "Keyboard & Character Viewer" at the top of the input method list on the left, and "Show Input menu in menu bar" at the bottom right. Then whenever you need a Unicode character, select "Show Character Viewer" from the input menubar. By default it browses by human-readable script/glyph categories that do not exactly correspond to the Unicode code tables, but changing the "View:" mode to "Code Tables" you can see the familiar ranges like "20D0 Combining Mark for Symbols; 2100 Letterlike Symbols" etc. You can also search by a string match against the long Unicode name, or by similar shapes.
