Ahhh, Masochism is still rife in the Amiga comunity I see ;-)
68K asm is actually quite fun, though I'm loathed to go near asm now... C++ really makes you life so much easier!
Paul's book is little more than a 68000 ref, wikipedia probably has a guide that will work for you... Other than painfully learning about addressing modes and setting up stack frames, there is not really much to learn... Make sure you get a good ref of the Amiga chipset regs... And you are away!
$0.02: My advice, learn C and SDL ;-)
