There's no problem with correctly written 1.3 software running under 2.0; as
long as you're not counting on private parts of structures looking the same,
or similar dirty tricks, you're in great shape.  For example, every program
I've written that doesn't depend on some 1.3 trick (eg, SetFont) or something
unsupported under 1.3 (eg, SetCPU V1.5, which ran into problems since it 
dealt with cache control issues that 2.0 solved differently) work just great.

I have only used it under 1.3.  While I didn't have any trouble with the 
resulting code, I did have some troubles with the C++ compiler.  It wanted
a heck of alot of stack (512K worked good) to avoid some crashes, and yet
it still had a problem with crashing on syntax errors.  The biggest problem
is the lack of a debugger -- once you're used to using a decent source level
debugger, you don't want to go back to "printfs" (or cout << for that matter).

I was actually surprised they included a text on the C++ language; most
compilers only discuss the differences between their implementation of
the language, if any, and probably list all library functions.  I wouldn't
have minded a few details on some of the rather esoteric stuff (for 
example, a way to replace the C++ allocator with my own, globally) but 
overall, I didn't find the docs that bad.
