1: As I understand things, you haven't compiled your code (yet). Simple
syntax errors, typically caught by a compiler, can occasionally cause
problems for ctags.  Assuming that you've gotten rid of your "tags"
folder so that the ctags can successfully generate a "tags" file, try
running ctags on your C files one at a time.  Does that work (ie. tags
are produced)?  Note that each invocation of ctags will wipe out the
previous work, so this is not a suggestion of how to generate all the
tags you want, rather a way to find what files are causing issues for ctags.

2. Only when you feel the need -- ie. when you've installed new
functions, changed functions' argument lists/types, etc.  Of course,
ctags can tag more than just functions -- local typedefs, etc.

3. When in vim, and editing one of your source files, use  :tag
FUNCTIONNAME , for example, with FUNCTIONNAME being one of your
functions' names.  That will exercise your ctags feature (assuming you
have +tag_binary as a feature).
  For cscope, first check that you have +cscope as a feature (vim
--version).  If you do, then read up on  :help cscope.
