A very nice map. Looks great. I've always been very partial to SS2 myself.

Not as a finished feature built into the program, but you can do this using a Macro.

The Large Exports annual contain such a macro with explanations (the end result with this macro is to combine the individual tiles into one large image, but the start of the macro exports the map as smaller tiles.)

Check with support. If you already own CC3+, they might provide you a copy of CC3 or find another way to provide you with a solution for getting the symbols.

That CAD Blocks site has a lot of good stuff. I've added it to the list in the Free Symbols resource thread.

These CAD blocks are actually ready to use symbol catalogs, which is very neat. I first thought I would have to resort to just copy/paste from the drawing, but load them up as a symbol catalog, and they show up as proper symbols.

Note that if it is a single map, reinstalling will NOT help, as that won't change your map.

Just reinstalling the latest update won't help when restoring files to default, as that only replaces files contained in the update, i.e. things that have been updated since release, to restore original files you need to run the original installer (CC3+ base or add-on, depending on what you want to fix), and then re-run the latest update after doing that.
