Suggestions on where to start programming needed

>What I'd really like is a hands on book (or online tutorial) that gradually introduces me to programming for the Amiga. I can find my way around C, but what I'd really like to try is 68000 assembler programming.

If you have not found an Assembler yet, you can try the MPDOS Pro which has a built-in 68K Assembler and you can save it to floppy disk and read it into Amiga via PC file transfer programs or cross-compile and "cross-execute" it with the floppy simulator & cable.  

Easy to start off with a simple working program like:

BCHG #1,$BFE001
RTS

and then build on it.

I should have mentioned that the MPDOS Pro w/68K ASM compiler is included with the floppy simulation cable if you really want to program real-time or low-level stuff by taking complete control over the amiga machine:

It includes some sample source code as well for making boot block image disks directly from your 68K ASM instructions(image disks that are 1024 bytes long).  You can then also write the boot blocks to your real (physical) floppy drive if you daisy chain it with the simulated drive (assuming you have some sector copier).
