Answering your questions in reverse order:
1) m68k-rtems-objcopy --output-target srec o-optimize/hello.exe 
hello.srec

2) To run from flash you need to use a different linker script.  Have a 
look at the linkcmds.prom script to get an idea of what you need to do.  
Running from flash is quite a bit slower than running from RAM so you 
might want to look into writing a small bootstrap program which sets up 
the 68360 memory configuration and then copies the real executable 
(hello.exe) from flash to RAM for execution.
