If you don't know C that well, maybe just learn C30 specifically.  Think of
each embedded C implementation as a different language based on the
principles of C.  On small embedded systems it's more important to get
things done than worry about compatibility to some standard that doesn't fit
small systems anyway.

You will have to learn "real" C when you go to try it on a big platform,
like a PC, where the standard makes some sense and is generally adhered to.

To the manual, of course.  If you already know ASM30, then start with C30
from that basis.  The C30 subroutine linkage and stack use model are
reasonable (unlike C18).  Read the C30 manual and write a simple subroutine
you call from assembler.  That will give you a great understanding of how
things work.  From there you can write more and more parts of your project
in C30 as you wish.  You will probably find C30 more applicable to higher
level control where fancy data structures are useful, and ASM30 easier for
low level bit twiddling and where speed is critical.
