You might want to loosen all of your rockers and shafts before loosening the cam nut - that's the best way to minimize the chance of valve-piston collisions. Try this order:

-loosen rockers as far as you can
-use impact wrench to loosen cam nut - don't let the engine spin backwards - have someone hold the crank with a breaker bar
-compress chain tensioners with clamp, remove
-remove cam sprocket, washers, retaining plate, etc., etc.

As SCadaddle noted - I did a cam-timing dry-run before disassembling, found the timing was retarded outside of spec, which I since learned is due to chain "stretch". This was a really good way to get comfy with the cam-timing process.
Good luck!
