The `ram' segment in the default gen68360 linkcmds script contains:
text (and C++ constructors/destructors/etc.)
bss (and exception vector table, etc.)
The workspace is set up after the stack.

Yes. The networking example programs show how to do this. The
following line added to your application Makefile will set up a 1
Mbyte heap (assuming your BSP works like the gen68360 linkcmds).
CFLAGS_LD += -Wl,--defsym -Wl,HeapSize=0x100000
