Chez, without looking at your manual and seeing what these modes are all about it's difficult to say.The honest truth though is all these fancy modes are there to help people who don't have a basic understanding sufficient to make these settings themselves, and it really isn't that difficult.
My Canon 20D has umpteen modes I'll never use including a 'Slow Flash Sync' mode. It also has a 'Landscape' mode, but it isn't rocket science to understand that all it does is bias your exposure in favour of smaller apertures for DOF. The 'Action' programme will simply bias in favour of faster shutter speeds.
These programmes are just gimmicks. The only modes you need are Manual, Aperture Priority and Shutter Priority.... honestly.
They can be useful sometimes and convenient, but they're a real bar to you progressing and actually understanding what you're doing.
Forget the funny modes and you'll be OK.
